KYW CRYSTAL NO FURTHER A MYSTERY

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant compared with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values effectively under 100 fs are actually achieved with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
