Product: Transmission Gratings for Pulse Compression, High Power Beam Combining and Spectroscopy

The most important properties of pulse compression gratings are high diffraction efficiency and low wave front deformation due to multi-pass use requirements for the gratings. The laser pulse compression transmission grating is based on LightSmyth’s record-breaking transmission grating platform. High diffraction efficiency (95% typical) allows our customers to minimize optical losses in the system, which is especially critical for high energy lasers.

Advantages:

  • Exceptional diffraction efficiency for selected polarization
  • Special design for broad passband and low angular sensitivity
  • Ultra-polished quartz substrate minimizes wave front deformation in transmission
  • Uses only fused silica and highly robust dielectric materials
  • No polymers or organics are used
  • Each grating is a master; ultra-low scatter
  • Extremely precise line density (line density uniformity <0.001 lines/mm)

Applications:

  • Pulse compression of pico- and femto-second pulses
  • High power lasers
  • Spectral beam combining and beam steering
  • Remote optical sensors and spectroscopy

Specifications
Grating will perform with high efficiency over significantly larger spectral range and range of angles. Wavefront error <0.2 λ at operational wavelength over 25mm.

Notes 1 Gratings will be highly efficient over larger range of angles – please inquire.
2 P-polarization: incident electric field vector perpendicular to grating lines.  S-polarization: incident electric field vector parallel to grating lines.
3 For gratings supporting both S and P polarizations, the diffraction efficiency is the average efficiencies of S and P polarization at any given wavelength
