Optics for High-power Fiber Lasers Feature Low-absorption Coating

Mate Laser Technologies has introduced 1 Micron Optics for high-power fiber lasers. The products include lenses, protective windows, and nozzles for several laser system brands.

The optics feature extremely low-absorption, fused-silica substrates. The low-absorption, antireflective coatings on the lenses and windows have a high laser damage threshold. The low-absorption feature helps ensure high cutting quality without thermal lensing and focus shift, the company states.

The fiber optics are suitable for use in 1-micron applications from 1,030 to 1,080 Nm with absorption of less than 50 PPM at 1.03 to 1.08 microns, a pinpoint focal length tolerance of ±0.5 percent, and laser damage threshold higher than 10 J.
