TOP KYW CRYSTAL SECRETS

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is quite huge when compared with that of Yb:YAG. This enables for extensive wavelength tunability and for Substantially shorter pulse durations from method-locked lasers. Values effectively under 100 fs have already been attained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW
