AN UNBIASED VIEW OF KYW CRYSTAL

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very huge when compared with that of Yb:YAG. This allows for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively beneath 100 fs are already realized with passive manner locking.This distinctive characteristic of ultrafast pulses permits nonli
