FACTS ABOUT KYW CRYSTAL REVEALED

The get bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant compared with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values properly down below 100 fs have already been realized with passive manner locking.The Yb-doped potassium yttrium tungstate (Yb:K
