KYW CRYSTAL SECRETS

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is very big when compared with that of Yb:YAG. This permits for huge wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values properly down below one hundred fs are already reached with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KYW
