RUMORED BUZZ ON KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant compared with that of Yb:YAG. This enables for huge wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values very well below 100 fs are already achieved with passive mode locking.The comparison with glasses is appropriate Considering that
