THE KYW CRYSTAL DIARIES

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in contrast with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively under one hundred fs are obtained with passive manner locking.This one of a kind attribute of ultrafast pulses permits nonline
