DETAILS, FICTION AND KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather huge when compared with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from method-locked lasers. Values properly underneath 100 fs happen to be attained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in co
