Diffraction Grating for Laser Systems LA Series

Features

  • 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.
