GETTING MY KYW CRYSTAL TO WORK

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very big in contrast with that of Yb:YAG. This permits for extensive wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values very well below one hundred fs have already been accomplished with passive manner locking.The Yb-doped potassium yttrium tungstate
