GETTING MY KYW CRYSTAL TO WORK

The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very significant compared with that of Yb:YAG. This allows for wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values perfectly down below a hundred fs are achieved with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) cryst
