The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, can be a remarkable materials that performs an essential position in laser technology. Its Key operate will be to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heartbeat
FIG. 4. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of the laser with a rectangular active ingredient for an output energy of seven hundred mW. The width of
Optical structure of the laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output in the radiation, WP is actually a half-wave plate, CL is really a collimating lens, FL is actually a focusing lens, AE is undoubtedly an Energetic element constructed from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC will be the output mirror, and SAM can be a semiconductor saturable-absorber mirror.
Just after air drying and subsequent cleaning by using a cotton cloth soaked in Alcoholic beverages, the film surface area confirmed no indications of peeling or scratches.
Raman, luminescence and transmission spectra expose optical attributes owing for the presence of thulium ions, and as a consequence the elements could possibly be further examined inside the scope of laser and luminescence applications.
Tungstates are likely to obtain high Raman coefficients (�?Raman scattering). Consequently, they're able to make important Raman get at average optical intensities. It is achievable to make use of the laser crystal by itself as being a Raman converter.

... Not only the position of crystal in the cavity but additionally the amplification axis of crystal affects the laser Procedure enormously, as the absorption and emission cross sections of your crystal are rather diverse according to the orientation from the crystal.
The thermal conductivity of common double tungstates is in the get to 3–4 W/(K m) �?which is not lousy when compared with other laser crystals (Despite the fact that numerous occasions fewer than for YAG), and rather huge compared While using the thermal conductivity of normal Eyeglasses.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at area temperature were being measured. The emission spectrum and lifetime on the three F 4 psyched state were established. Employing typical and modified Judd–Ofelt theories, the depth parameters as well as the radiative lifetimes have been calculated and superior arrangement Using the experimental results was attained for the two theories.
