RUMORED BUZZ ON KYW CRYSTAL

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very big when compared with that of Yb:YAG. This permits for wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values very well below 100 fs are already realized with passive manner locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) cryst
