THE SMART TRICK OF KYW CRYSTAL THAT NO ONE IS DISCUSSING

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW may be very substantial in contrast with that of Yb:YAG. This allows for large wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values effectively under 100 fs are already obtained with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
