Lidaris
LIDARIS is a high-tech company, which provides professional Laser-Induced Damage Threshold (LIDT) metrology services for companies that manufacture, trade or integrate laser optics. LIDT numbers are measured in house and enable to describe optical resistance (safe light intensity operation limit) of optical parts such as lenses, mirrors, windows or similar with intended use in high power laser systems. Thus, LIDT numbers are bringing evidence related to optics quality and help to make important decisions.
LIDARIS was founded in 2012 as a spin-off of the Vilnius University Laser Research Center by a group of scientists working intensively in the field of laser-induced damage phenomena. LIDARIS team gained more than 18 years of research experience in the field of laser-induced damage of optical elements and thin films. Currently LIDARIS acts in the global market serving European, American and Asian companies - the leaders of today's laser market, including manufacturers, suppliers of optics and laser systems and Space Agencies. More than 90 organizations use LIDARIS services on a daily basis. Scientific contributions of LIDARIS members were awarded by the SPIE Laser Damage community. The dynamic team is committed to delivering its customers with state-of-the-art knowledge required to survive laser damage.
The formation and growth of Laser Induced Damage depends on:
- laser irradiation parameters (such as wavelength, pulse duration, spatial beam profile, temporal pulse profile , repetition rate);
- environment conditions (such as: air, vacuum, temperature, contamination);
- material properties (such as intrinsic and extrinsic defects of the optical component, preparation method and shape).
Thus, Laser-Induced Damage Threshold (LIDT) of the optical elements should be tested at the same conditions as they are intended to be used.
LIDARIS provides wide range of irradiation conditions. Testing is available:
- At nano-, pico-, femtosecond pulse regimes;
- From UV to IR spectral range;
- In different environments: air, vacuum, cryogenic temperatures.
Another important factor in LIDT metrology is testing protocol. Lidaris provides standard (ISO 21254-1,-2,-3, and -4) and custom Laser-Induced Damage Threshold (LIDT) testing procedures. Non standardized testing such as R-on-1, micro-focus, rear-side and measurements in vacuum are available on demand. For the convenience of our customers, we also provide additional services such as total integrated scattering test, Group Delay Dispersion (GDD) measurements, crystal efficiency and transmission tests.
