High-Power Laser Mirror

Koshin has developped the high-power laser mirror which has one of the largest laser-induced damage threshold (LIDT).


The Koshin’s mirrors are applied for the laser processing machines and the laser equipments in the laser-fusion experiment　facilities. 

We offer not only the fundamental YAG laser wavelength but also the second and the third harmonic wavelength.
