THE SMART TRICK OF KYW CRYSTAL THAT NO ONE IS DISCUSSING

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant compared with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values very well under 100 fs happen to be accomplished with passive method locking.The comparison with Eyeglasses is acceptable since
