Pulse Compression Transmission Gratings

Pulse Compression Grating

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. At more than 94% diffraction efficiency optimized for linear P-polarization, it 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
    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- see general specification sheet.
