Diffraction GratingsDiffraction Gratings for Laser Systems LA Series

DIFFRACTION GRATING for Laser Systems LA Series


• High diffraction efficiency
• Wide wavelength coverage
• Wide selection
• Customizable

These gratings are suitable for various laser applications (external resonator, external cavity, pulse control). Applying TM waves (S-polarization) *1, a high diffraction efficiency is expected for a wide range of wavelengths. The LA Series products are replicated using high-quality masters. All nine products in this LA Series are customizable for laser resistance, substrate, size and other customer requirements.
