FASCINATION ABOUT KYW CRYSTAL

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in comparison with that of Yb:YAG. This enables for huge wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values very well down below a hundred fs are already achieved with passive manner locking.The comparison with Eyeglasses is appropriate s
