The Yb:KYW crystal’s proficiency in light absorption at all over 981 nm helps make the crystal well matched for diode pumping. It really is further more enhanced by its amazing efficiency in this process, coupled with its very low quantum defect.

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers getting fiber output. To avoid spectral narrowing through amplification as well as corresponding lengthening of the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals ended up applied, Along with the spectral maxima on the amplification shifted relative to each other and with spectral profiling of the amplified radiation.
The monoclinic crystal constructions ends in a organic birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing materials to generate ultrashort (~ a hundred-two hundred fs) substantial electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser units.

Superior-electricity KYW Crystal repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
Even though ytterbium-doped laser achieve media normally exhibit a small quantum defect, ytterbium-doped tungstates permit for particularly smaller values. One example is, a 1030-nm Yb:YAG laser would Commonly be pumped about 940 nm, whereas Yb:KGW or Yb:KYW might be most competently pumped all around 981 nm.
