GETTING MY KYW CRYSTAL TO WORK

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely huge in contrast with that of Yb:YAG. This allows for broad wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values well below a hundred fs have been realized with passive method locking.This exclusive attribute of ultrafast pulses enables nonlinear optic
