The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is a outstanding content that plays a significant job in laser technology. Its primary function is to generate ultrashort pulses of light, spanning just a few hundred femtoseconds.

Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heartbeat

The absorption and emission spectra of Yb:KYW Crystals Screen robust peaks at 980 nm and 1030 nm, respectively, ensuring efficient energy conversion and superior overall performance in laser methods.

Optical structure of a laser with direct pumping Along with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output with the radiation, WP is a fifty percent-wave plate, CL can be a collimating lens, FL is usually a focusing lens, AE is definitely an active component made out of an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC is the output mirror, and SAM is really a semiconductor saturable-absorber mirror.

The monoclinic crystal structures results in a all-natural birefringence, assisting to steer clear of thermally induced polarization rotation and depolarization decline.

Raman, luminescence and transmission spectra reveal optical capabilities owing to the presence of thulium ions, and thus the resources may very well be further more examined during the scope of laser and luminescence purposes.

Spatial construction in the beam as well as the corresponding intensity profiles I at the output of your laser.

Substantial-energy repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes

While ytterbium-doped laser gain media commonly more info show a little quantum defect, ytterbium-doped tungstates enable for especially small values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped about 940 nm, whereas Yb:KGW or Yb:KYW may be most proficiently pumped all-around 981 nm.
