NOT KNOWN DETAILS ABOUT KYW CRYSTAL

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very huge compared with that of Yb:YAG. This allows for huge wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values properly underneath 100 fs are already accomplished with passive mode locking.This one of a kind characteristic of ultrafast pulses ena
