RUMORED BUZZ ON KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely big in comparison with that of Yb:YAG. This enables for vast wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values well underneath a hundred fs have been achieved with passive manner locking.The comparison with Eyeglasses is suitable Because th
