KYW CRYSTAL SECRETS

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values properly underneath a hundred fs have been accomplished with passive method locking.This exceptional characteristic of ultrafast pulses

.. [Present whole summary] parametric oscillator. The two independently targeted beams have been designed to overlap In the crystal. The focusing parameters of the two beams have been with regard to the exact same. The concentrating purpose produced by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals in an ef
