The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a extraordinary material that plays an important job in laser technology. Its Principal perform is usually to generate ultrashort pulses of light, spanning just a few hundred femtoseconds.

Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse

The absorption and emission spectra of Yb:KYW Crystals Exhibit solid peaks at 980 nm and 1030 nm, respectively, making sure economical Vitality conversion and substantial general performance in laser methods.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical aspects as many as a hundred% of Yb-doping can be achieved. This unique attribute permits ytterbium to go ahead and take place of yttrium with nearly no disruption towards the crystal’s lattice.

Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser obtain medium. It absolutely was in fact Utilized in the 1st continuously working crystal laser.

Raman, luminescence and transmission spectra reveal optical options owing on the presence of thulium ions, and thus the materials could possibly be further more analyzed during the scope of laser and luminescence purposes.

Spatial framework in the beam as well as the corresponding intensity profiles I at the output with the laser.

... at 50 percent-peak had been generated in a check here very master oscillator with selfsynchronization of the axial modes, explained within our earlier write-up. 21 The new version of your laser, compared with that explained in our before write-up, utilized an Yb:KYW crystal having an N pcut (optical axis N p on the index ellipsoid was parallel towards the propagation way on the laser radiation), Using the polarization of your produced radiation directed together the N m axis.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the related sizes of such chemical things as many as 100% of Yb-doping could possibly be accomplished.
