The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather substantial compared with that of Yb:YAG. This permits for broad wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values very well underneath one hundred fs are already realized with passive manner locking.
The comparison with glasses is suitable since the big gain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We existing a twin-crystal Yb:KGW laserthat iscapable to work like a Q-switched oscillator with output ability around 24 W and pulse duration of twenty ns,or to be a regenerative amplifier with output electric power up to 21 W and pulse duration below 200 fs right after compression of chirped pulses. Both lasers have superb beam good quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, making certain successful Vitality conversion and high general performance in laser systems.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the comparable sizes of such chemical things around a hundred% of Yb-doping could possibly be attained. This exclusive attribute permits ytterbium to go ahead and take put of yttrium with virtually no disruption on the crystal’s lattice.
The monoclinic crystal constructions leads to a purely natural birefringence, assisting to avoid thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra reveal optical characteristics owing towards the existence of thulium ions, and so the components could be even further click here examined during the scope of laser and luminescence purposes.
Tungstates are likely to obtain superior Raman coefficients (�?Raman scattering). For that reason, they can produce important Raman achieve at reasonable optical intensities. It can be done to make use of the laser crystal alone as a Raman converter.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the identical dimensions of such chemical elements around one hundred% of Yb-doping may very well be obtained.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature were being measured. The emission spectrum and lifetime on the three File four thrilled point out have been determined. Utilizing normal and modified Judd–Ofelt theories, the depth parameters along with the radiative lifetimes have been calculated and very good arrangement with the experimental benefits was acquired for both of those theories.
