Major Features

Optics for Solid-State Lasers, Major Features
High laser resistance
Laser damage threshold value >20J/cm2 @1064 nm, 1ns
Superior stability
Transmittance variation: 200 ppm/℃
Spectrum shift rate: 20 ppm/℃
(By means of ion assist deposition)
Low optical loss
R > 99.98% @1064 nm
Low absorption and low scattering

SOC attempts to improve not only the high damage resistance but also the stability. SOC developed mirrors suitable to kW-class high-power lasers, featuring low transmittance variation (ΔT/TO) reduced to 1/5 or less of traditional mirrors, and overturned the accepted idea that a thermally stable coating has low laser resistivity. SOC also selects processes most suitable to a variety of demands and supplies high-quality optics for solid lasers.

Application Examples

YAG laser bend mirror

Since establishing Japan's first coating technology for high-power lasers, SOC has offered proven dielectric multilayer bend mirrors at reasonable prices. Since the mirrors support a reflection band of 1030 to 1100 nm, they can also be used for fiber lasers.
