RUMORED BUZZ ON KYW CRYSTAL

The get bandwidth e.g. of Yb:KGW and Yb:KYW is rather significant compared with that of Yb:YAG. This permits for large wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values well below 100 fs happen to be accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in compari
