Application 
- Second harmonic generation

Second harmonic generators ASG800, ASG800-B and ASG1250 are developed for producing the coherent radiation at doubling frequency for femtosecond oscillator sources having output wavelength range at 800 nm (TiSa lasers) and 1.25 um (CrF lasers). Principles of operation are based on second harmonic generation technique and provides stable radiation with good beam quality and  small pulse broadening in fs scale.
