KYW CRYSTAL - AN OVERVIEW

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW may be very substantial compared with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively down below one hundred fs are already realized with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KY
