Avesta Project, femtosecond lasers and equipment Components Second Harmonie Generator ASG • High conversion efficiency • Small walk-off angle • Low beam divergence • No heating Product overview 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.
