AN UNBIASED VIEW OF KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values very well down below a hundred fs happen to be accomplished with passive mode locking.The comparison with glasses is acceptable For th
