Sapphire fiber laser windows from Laser Research Optics function as debris shields
- August 6, 2019
- Product Release
- Laser Cutting
Laser Research Optics has introduced sapphire fiber laser windows.
They are suitable for use as debris shields on high-power lasers from 4 kW up and have lower bulk absorption with about 30 times higher thermal conductivity than fused silica protection glasses, the company says.
Featuring Mohs 9 hardness, which is second only to diamond, they have A/R coatings on both sides to provide transmission of greater than 99.5 percent at 1.06 microns with more than 80 percent at 650-670 nm.
Reducing focus shift and the deterioration of beam quality, the windows can withstand steel splatter, flash, and debris. Available in 0.5- and 2.0-in. sizes, they have a 10-5 scratch-dig finish and ¼-wave transmitted wavefront.
