GETTING MY KYW CRYSTAL TO WORK

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather huge compared with that of Yb:YAG. This enables for extensive wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values perfectly below 100 fs are already accomplished with passive mode locking.This distinctive attribute of ultrafast pulses enables nonlinea
