GETTING MY KYW CRYSTAL TO WORK

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather large when compared with that of Yb:YAG. This permits for broad wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values well beneath one hundred fs are obtained with passive manner locking.This one of a kind characteristic of ultrafast pulses all
