The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a amazing materials that performs an important position in laser technology. Its Major purpose should be to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the pulse

This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with immediate longitudinal pumping by potent linear arrays of semiconductor injection lasers owning fiber output. To avoid spectral narrowing in the course of amplification and also the corresponding lengthening on the amplified pulse when it's compressed, a mix of two Yb:KYW crystals ended up used, With all the spectral maxima of your amplification shifted relative to one another and with spectral profiling on the amplified radiation.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important rare-earth-doped laser get medium. It was in reality Employed in the first continually running crystal laser.
FIG. one. Optical structure of the laser with direct pumping Along with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output
Spatial structure of the beam and the corresponding depth profiles I within the output of your laser.

Even so, the moment Nd3+:YAG turned commercially out there, the interest in CaWO4 dropped sharply. In later decades, particular other tungstate crystals began to catch the attention of loads of attention.
