A SIMPLE KEY FOR KYW CRYSTAL UNVEILED

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very massive when compared with that of Yb:YAG. This enables for wide wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values nicely down below one hundred fs are obtained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal
