NOT KNOWN DETAILS ABOUT KYW CRYSTAL

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is very massive as opposed with that of Yb:YAG. This permits for broad wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values properly underneath a hundred fs are actually achieved with passive manner locking.This exclusive characteristic of ultrafast pulses
