AN UNBIASED VIEW OF KYW CRYSTAL

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather significant in contrast with that of Yb:YAG. This permits for broad wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values very well down below a hundred fs have been attained with passive mode locking.This special characteristic of ultrafast pu
