4. Pulse Compression Transmission Gratings （脉冲压缩透射光栅）

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
