THE SMART TRICK OF KYW CRYSTAL THAT NOBODY IS DISCUSSING

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather large compared with that of Yb:YAG. This enables for wide wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values very well beneath a hundred fs are actually reached with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in
