FASCINATION ABOUT KYW CRYSTAL

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is very massive compared with that of Yb:YAG. This enables for wide wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values nicely beneath one hundred fs are obtained with passive manner locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, co
