Reliability of high-power lasers is to a large extend given by optical components used in them. Therefore, the knowledge of the quality of used components is essential for safe and reliable operation of laser systems. The LIDT (Laser Induced Damage Threshold) value indicates the maximum amount of optical energy (power) that component can withstand before damage occurs.
The HiLASE Centre offers LIDT services, thanks to unique laser sources (such as BIVOJ laser, 10J, 10ns, 10 Hz) under a unique regime with big top-hat spot and high energy. A number of LIDT procedures is available, based on ISO standard 21254 series or customized according to specific needs. We have established a Quality Management System in our LIDT laboratory and received the ISO 9001 CERTIFICATE.
