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 95% 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.
- 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.
