Product overview:Third harmonic generators ATsG800 and ATsG800-C are developed for producing coherent radiation at doubling and tripling frequency for TiSa femtosecond oscillator and amplifier, respectively. The input wavelength range is supposed to be from 750 to 900 nm. Principles of work are based on second and sum-frequency generation technique and provides stable radiation with good beam quality and small pulse broadening in fs scale.
