KYW CRYSTAL NO FURTHER A MYSTERY

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This enables for extensive wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values very well underneath 100 fs have already been reached with passive mode locking.This exclusive attribute of ultrafast pulses enables
