LASER PROCESS

What is laser ablation?

Laser ablation is a removal process that removes paint, coatings, thin films or base material from a surface with a focused, pulsed laser beam, layer by layer and without contact or chemicals. Each pulse removes a precisely controlled amount, so a coating can be stripped to an exact shape or depth while the material underneath stays intact. While laser ablation primarily denotes non-contact laser cleaning, the technique is also utilized for precision marking, surface texturing, engraving and cutting.

Laser ablation is also the starting point of a large amount of industrial processes in many application fields like manufacturing, microelectronics, automotive, diagnostics and medical. Laser ablation is great for a wide range of materials, including plastic, metal, ceramic, and even biological tissue to produce things like Nano-materials or to fabricate superconducting materials, solar cell manufacturing , machining day and night knobs in automotive sector, ablating of PEEK for implants and many more.

Cleaning Selective ablation Laser cleaning Removes rust, paint, oxide and oil and stops at the substrate, because contaminants ablate at a lower energy than the metal. Rust, paint, oxide and oil removal.

Markolaser Laser Ablation Machine: URSA

URSA is Markolaser’s enclosed Class 1 laser workstation for precision laser ablation. It removes paint, lacquer, anodising and thin coatings to an exact pattern or depth. Typical jobs include day-and-night symbols on automotive switches and dial rings, codes on coated parts, and selective coating removal before bonding. The same machine also marks, engraves, textures and micro-drills, so one workstation covers several processes. Its modular design integrates easily into your existing production lines, and it can be customised to your part, process and output requirements.

Why URSA suits laser ablation?

  • The right wavelength for each coating: fiber, UV, green or CO₂ laser source, chosen to match how the coating and substrate absorb the beam.

  • Symbols aligned to every part: a vision system for positioning and recognition places the ablation pattern accurately on each part, which backlit symbols need.

  • Curved and 3D surfaces: a programmable servo Z-axis (±50 µm) and 2D-on-3D software keep knobs, rings and contoured panels in focus.

  • Cylindrical parts: a rotary axis for knobs, tubes and round components.

  • Clean, safe operation: a Class 1 enclosure, with an optional Force 3+ fume extractor for ablation fumes and particles.

  • Ready for production lines: a modular design, side pass-through loading, an optional pallet system, and standalone control over Ethernet or RS232.

Frequently Asked Questions

1 What is laser ablation?

Ans: Laser ablation is a reliable, efficient and cost effective process of removal of layers from solid metals or industrial compounds using laser beams for high precision to expose the covered layer. Common coating removals include perylene, poly-amides, silver chloride and gold, but many others are possible. The amount of layers that is removed depends on the intensity, pulse length, and wavelength of the laser, and the material itself.

2 How does laser ablation work?

Ans: A short laser pulse is absorbed in a thin surface layer faster than heat can spread into the part. The layer passes its ablation threshold and leaves the surface as vapour, plasma or fine particles. Pulse energy, pulse length, wavelength, scan speed and the number of passes control how much is removed.

3 What materials can be processed using a laser ablation machine?

Ans: A laser ablation machine can effectively work on a wide range of materials including metals (steel, aluminum, gold), plastics (like PEEK), ceramics, glass, and even in medical research. For example, it’s used to fabricate solar cells, microelectronic components, nanomaterials, and even automotive knobs. Ablation lasers provide fine control when removing paint, insulation, coatings, or contaminants—especially in industries where substrate protection is essential.

4 Are laser engraving, marking and cutting types of laser ablation?

Ans: Some are. Laser engraving, deep engraving and laser texturing are ablation, because they vaporise material. Marking is ablation only when it removes a coating or engraves the surface; annealing, foaming and carbon-migration marks change colour without removing material. Cutting is ablation for films, foils and micro-parts, but most sheet-metal cutting melts the metal instead.

5 What is the difference between laser ablation and laser cleaning?

Ans: Laser cleaning is one application of laser ablation. Cleaning removes unwanted layers such as rust, oil or oxide across a surface and stops at the substrate. Laser ablation as a production process removes material to a defined pattern or depth, such as backlit symbols, selective coating removal or thin-film scribing.

6 Which materials and coatings can be laser ablated?

Ans: Common layers include paint, lacquer, anodising, PVD and metal films, parylene, polyimide, wire enamel and oxides. Substrates include steel, aluminium, copper, gold, plastics such as ABS, PC and PEEK, glass and ceramics. Results are cleanest when the coating and the substrate absorb the laser very differently.

7 What is the role of laser ablation in EV battery manufacturing?

Ans: Laser Ablation finds many applications beyond Primary cleaning. It is a versatile, non-contact technology crucial for maximizing the performance, enhancing conductivity, safety, and sustainability of EV batteries throughout their entire lifecycle. The primary role of laser ablation in EV battery manufacturing is to ensure ultraclean and smoother surfaces and precision structuring for optimal performance, while also supporting sustainable end-of-life processes. Laser ablation ensures Selective removal of organic and inorganic contaminants (dust, oxides, residue) from busbars, tabs, and bonding areas. Reduces critical defects like short circuits and lithium dendrite formation, boosting bond strength and consistency for battery reliability.

8 Which laser is best for laser ablation?

Ans: It depends on the layer. Fiber lasers (1064 nm) suit paint, anodising and coatings on metal. UV lasers (355 nm) suit polymers, thin films and heat-sensitive parts. Green lasers (532 nm) suit reflective metals and thin films. CO₂ lasers suit organic coatings and insulation. Femtosecond lasers ablate with almost no heat effect.

9 What is day-and-night laser ablation?

Ans: Day-and-night ablation removes the top paint layer from a translucent plastic part, such as a car switch, knob or appliance panel, in the shape of a symbol. By day the symbol shows in the base colour; at night the backlight shines through it. The paint must be removed completely without burning the plastic.

10 Does laser ablation damage the base material?

Ans: Not when the process is set up correctly. Coatings usually ablate at a much lower energy than the material underneath, so the laser is set between the two thresholds and stops at the substrate. Ultrashort pulses reduce heat effects further, which matters for thin, heat-sensitive or medical parts.

11 Is laser ablation better than chemical stripping or mechanical removal?

Ans: Yes, For precise, selective work. Laser ablation uses no chemicals, abrasives or masks, removes coating only where programmed, and gives the same result on every part. Chemical and mechanical methods can be cheaper for large areas where precision does not matter, but they create waste and can damage fine features.

12 Is laser ablation safe for operators?

Ans: Yes, with the right enclosure and extraction. Markolaser’s URSA ablation workstation is Class 1 enclosed, so no laser light escapes during processing. Ablation produces fumes and fine particles, so the system needs fume extraction and filtration. Open or handheld setups need laser safety goggles for the correct wavelength and a controlled area.

13 How much does a laser ablation machine cost in India?

Ans: Most Markolaser laser ablation systems cost between 2 - 4 Million INR , depending on the laser source, power, enclosure, automation and software. A standard enclosed workstation sits at the lower end; automated cells with part handling and vision alignment cost more. Send your part for a test and a configuration-specific quote

14 Can I test my parts before buying, and does Markolaser supply across India?

Ans: Yes. Send your parts through the Markolaser sampling form and we will test-ablate them, share the results and recommend a laser source and machine. Markolaser designs and builds its systems in Gurugram and supplies and supports them across India, including Delhi NCR, Bengaluru, Chennai, Pune, Mumbai, Gujarat and all other manufacturing hubs in India.

15 Can laser ablation be used to prepare surfaces before coating?

Ans: Yes. Laser ablation removes oil, oxide, release agents and old coatings, then ablates the surface itself in a defined pattern to roughen it. Both steps use the same pulsed laser, so a part can be cleaned and textured in one setup before coating, painting or bonding.

16 What is laser micro-material removal?

Ans: Laser micro-material removal is laser ablation on a micron scale. Each pulse removes a very small, controlled amount of material, so fine grooves, holes, textures and structures can be made precisely. Pulse energy, pulse length, wavelength and the number of passes set the depth and shape of each feature.

17 Which materials can be made into nanoparticles by laser ablation?

Ans: Almost any solid that can be made into a target can be ablated into nanoparticles. The clearest examples are gold, silver and copper (metals), titanium dioxide (an oxide) and silicon (a semiconductor). The laser ablates the solid target in water or a solvent, and the ejected material cools into nanoparticles.
