Pulse Compression Transmission Gratings
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
