KYW CRYSTAL - AN OVERVIEW

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is very huge when compared with that of Yb:YAG. This allows for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values nicely down below a hundred fs are actually achieved with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when c
