There are various application areas from research to wide range of industries that we believe our lasers can make difference.
Ultrafast lasers are great tools to make sub-wavelength periodic structures on different materials on indefinitely large areas. Different periodic structures can be generated on various materials such as titanium, stainless steel, copper, slicon, etc. Stitching the structures is also possible that no other lithography technique can offer. Ultrafast laser nanostructuring is a promising tool to cover large areas in industry with nanostructures with extreme uniformity, easily and cost-effectively. Just to name a few applications: mold processing, solar cell surface structuring, hydrophobic/hydrophilic and oleophobic surface generation.
The basic tool of nonlinear imaging is a very fast laser that is able to generate picosecond or femtosecond pulses. The most widely used lasers for this purpose are solid state ultrafast lasers that can offer high pulse energies with high tuning capability in wavelength. Ultrafast fiber lasers are now replacing these lasers with their extreme stability and reliability. Since the imaging is just about focusing to tightest spot, ultrafast fiber lasers are the best option with their very high beam quality that no other laser types can satisfy. Lumos Laser offer a high parameter adjustability range in terms of wavelength (400-1100 nm), pulse energy (from pJs to uJs), pulse duration (from 50 fs to nanoseconds) that nonlinear imaging modalities require.
Ultrafast lasers are so precise in 3D that you can ablate an organelle inside a cell without damaging the cell membrane. Ultrafast fiber lasers that Lumos offers are perfect tools for understanding the underlying mechanism of biological processes since they are highly adjustable in many parameters. For tissue processing purpose, ultrafast fiber lasers with high repetition rate burst mode gives the best results for ablation rate with very low pulse energies. This makes the burst mode ultrafast fiber lasers as a candidate for next generation ophthalmology lasers.
One of the biggest rules of a meaningful scientific measurement is to use a measurement tool that is shorter than the process to be measured. So, the lasers that can generate down to 50 fs is a great tool to understand molecular level processes. Processes such as CARS, THz spectroscopy, time-correlated single photon counting, pump-probe spectroscopy are just a few of the examples for spectroscopy techniques that ultrafast lasers are used in.
Medical Device Manifacturing
Stents made of metals and polymers need to be processed with very high precision on micrometer scale, without any substantial burrs. Another issue is to process stents without carbonization in order to protect the biocompatibility of the stent. Heatless and precise processing of ultrafast lasers make them perfect tools for this purpose. Dental implants are one of the other areas that the ultrafast lasers can be applied to. Direct processing capability of ultrafast laser structuring offers the same structuring capacity without any residues on implants, and hence no losses. Femtosecond lasers are the best options for highly repeatable manufacturing technology to mass-manufacture implants with high precision and high aspect ratio with minimal burrs.
Glass & Sapphire Processing
Ultrafast lasers usage in glass processing is increasing extremely fast. Unlike the other laser types and glass processing methods, ultrafast lasers do not melt or cause micro-cracks on the material, which makes them a reliable tool to process durable glass that needs high precision processing. In addition to cutting, other applications that ultrafast lasers can offer on glass are: engraving, marking inside glass, 3D processing, waveguide generation, selective laser etching, glass strengthening, hydrophobic/hydrophilic surface generation, etc. Ultrafast lasers offer the same processing capability on sapphires with same quality and are finding application areas on many other transparent materials too.
