FASCINATION ABOUT KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant in contrast with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values properly below 100 fs are actually attained with passive method locking.This one of a kind attribute of ultrafast pulses enables non
