RUMORED BUZZ ON KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather large as opposed with that of Yb:YAG. This allows for broad wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values nicely beneath 100 fs have already been reached with passive method locking.The comparison with Eyeglasses is suitable since the sig
