DETAILS, FICTION AND KYW CRYSTAL

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is rather big as opposed with that of Yb:YAG. This permits for vast wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values very well below a hundred fs have been reached with passive mode locking.This exceptional attribute of ultrafast pulses permits non
