AN UNBIASED VIEW OF KYW CRYSTAL

The get bandwidth e.g. of Yb:KGW and Yb:KYW is very significant in contrast with that of Yb:YAG. This enables for extensive wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values very well down below a hundred fs are actually obtained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) cr
