The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is often a remarkable materials that plays a crucial position in laser technological innovation. Its Key functionality should be to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Screen sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electrical power conversion and higher performance in laser systems.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of identical dimensions of such chemical elements as much as 100% of Yb-doping could possibly be attained. This exclusive characteristic permits ytterbium to take the location of yttrium with nearly no disruption for the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test involved implementing a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed totally after which taken out vertically. This treatment was carried out 3 times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical characteristics owing into the existence of thulium ions, and therefore the materials may very well be further more examined in the scope of laser and luminescence purposes.
Spatial composition with the beam plus the corresponding intensity profiles I with the output on the laser.
... at fifty percent-top have been produced in a very master oscillator with selfsynchronization on the axial modes, explained in our earlier article. 21 The new version of your laser, as opposed to that explained in our before short article, utilized an Yb:KYW crystal with the N pcut (optical axis N p of the index ellipsoid was parallel towards the propagation route of the laser radiation), with the polarization on the produced radiation directed together the N m axis.
... Don't just the placement of crystal inside the cavity but also the amplification axis of crystal has an effect on the laser operation tremendously, since the absorption and emission cross sections in the crystal are really different according to the orientation of the crystal.
