The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, can be a remarkable materials that plays a very important purpose in laser technologies. Its Major operate will be to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
time. Crystals of the compound melts congruently at 1007 oC, however soften crystallization of top quality crystal is not possible because of period transition at ~920 oC. The highest seeded Remedy method from
Color-coded reflectivity of a Bragg mirror for a functionality of wavelength and angle in the incident beam.
This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers possessing fiber output. To avoid spectral narrowing in the course of amplification as well as the corresponding lengthening in the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals have been employed, Using the spectral maxima of the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
The monoclinic crystal buildings ends in a organic birefringence, helping to steer clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra reveal optical functions owing into the existence of thulium ions, and for that reason the components could be even further researched within the scope of laser and luminescence apps.
5 mm other than the middle of the beam caustic. So as to check the method matching simulation, we executed the experiment with Ng-Reduce crystal oscillator, which was made Earlier and in a identical problem with simulation [11]. As shown in Figure 3(b) with pink dots and line, the CW output electric power is highly dependent on the situation of laser crystal as well as experimental result coincides effectively with simulation result. Like a Notice, multimode Procedure happened in experiment in the event the measurement of your pump beam is bigger than TEM00 cavity mode and it will cause increased CW output power in the displacement area down below three.five mm.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to very similar sizes of such chemical aspects around 100% of Yb-doping may very well be attained.
When ytterbium-doped laser gain media usually exhibit a small quantum defect, ytterbium-doped tungstates enable for notably modest values. Such as, a 1030-nm Yb:YAG laser would Ordinarily be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW can be most competently pumped all over 981 nm.

The polarized absorption spectra of check here Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature ended up calculated. The emission spectrum and life span from the 3 F 4 fired up condition ended up identified. Using regular and modified Judd–Ofelt theories, the intensity parameters as well as the radiative lifetimes have been calculated and very good arrangement Along with the experimental effects was received for both equally theories.
In this article you are able to post questions and feedback. As far as they get acknowledged through the creator, they're going to look above this paragraph together with the creator’s response. The author will settle on acceptance based upon specified criteria. Fundamentally, the issue has to be of sufficiently broad fascination.
