GETTING MY KYW CRYSTAL TO WORK

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values properly below 100 fs have been reached with passive mode locking.This special characteristic of ultrafast pulses allows nonlinear opt
