The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a remarkable material that plays a crucial part in laser know-how. Its Most important functionality should be to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
The Yb:KYW crystal’s proficiency in gentle absorption at around 981 nm helps make the crystal compatible for diode pumping. It is actually further Increased by its outstanding efficiency in this process, coupled with its reduced quantum defect.

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by impressive linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening on the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals ended up utilized, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling of the amplified radiation.
Adhesion Examination Compliant with MIL-C-675C military services expectations, an adhesion test concerned applying a tape that meets LT-90 specs onto the lens film layer. The tape was affixed totally after which eliminated vertically. This procedure was performed three times, causing no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are utilised as lasing resources to create ultrashort (~ 100-two hundred fs) large electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser systems.
five mm besides the center from the beam caustic. To be able to check the manner matching simulation, we carried out the experiment with Ng-Reduce crystal oscillator, which was created previously As well as in a identical condition with simulation [eleven]. As shown in Determine 3(b) with purple dots and line, the CW output electrical power is very dependent on the posture of laser crystal along with the experimental outcome coincides very well with simulation outcome. To be a Be aware, multimode Procedure transpired in experiment in the event the size on the pump beam is bigger than TEM00 cavity method and it will cause higher CW output electricity during the displacement location below 3.5 mm.
... at fifty percent-height were created in the grasp oscillator with selfsynchronization from the axial modes, explained within our earlier posting. 21 The new version from the laser, unlike that explained in our previously post, made use of an Yb:KYW crystal using an N pcut (optical axis N p of the index ellipsoid was parallel for the propagation direction with the laser radiation), With all the polarization from the produced radiation directed together the N m axis.
Having said that, when Nd3+:YAG grew to become commercially out there, the interest in CaWO4 dropped sharply. In later on several click here years, sure other tungstate crystals began to catch the attention of a lot of focus.

Li2WO4-WO3 flux was effectively utilized lowering the growth temperature beneath 900 oC. In accordance with single crystal x-ray measurements, the crystal corresponds towards the P2/n space group.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature were calculated. The emission spectrum and life span from the 3 F four psyched state were being determined. Making use of regular and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes ended up calculated and superior settlement with the experimental results was received for the two theories.
Simultaneously, a shorter laser wavelength is often acquired; it is possible to work by using a quantum defect effectively below 1%. As being a consequence, the warmth era is usually so smaller this partly compensates the decrease thermal conductivity.
