RUMORED BUZZ ON KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely big in contrast with that of Yb:YAG. This allows for wide wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values well below a hundred fs have been obtained with passive manner locking.The comparison with Eyeglasses is acceptable For the reason that signif
