HiLASE offers LIDT (Laser Induced Damage Threshold) services, thanks to unique laser sources (BIVOJ laser, 10J, 10ns, 10 Hz) under a new testing regime with big spot size and high energy density. Laser Induced Damage Threshold (LIDT) is a key parameter for the optical components of high power laser systems and their beam distribution systems. The LIDT value indicates the maximum amount of energy (power) that a surface can withstand before damage occurs.
INDUSTRIES
