THE SMART TRICK OF KYW CRYSTAL THAT NOBODY IS DISCUSSING

The get bandwidth e.g. of Yb:KGW and Yb:KYW is very huge as opposed with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values nicely down below one hundred fs are already achieved with passive mode locking.The comparison with Eyeglasses is appropriate Because
