The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is often a amazing product that performs a very important role in laser technologies. Its Main perform would be to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Femtosecond laser dependant on Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heartbeat
Shade-coded reflectivity of the Bragg mirror as being a operate of wavelength and angle of the incident beam.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to identical sizes of such chemical features up to a hundred% of Yb-doping can be achieved. This unique attribute permits ytterbium to go ahead and take position of yttrium with just about no disruption to your crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C military specifications, an adhesion examination included making use of a tape that fulfills LT-90 specs onto the lens film layer. The tape was affixed totally after which taken out vertically. This method was carried out three times, causing no blistering or peeling.

five mm in addition to the middle here in the beam caustic. As a way to Verify the manner matching simulation, we done the experiment with Ng-Reduce crystal oscillator, which was developed previously As well as in a very same situation with simulation [eleven]. As proven in Determine three(b) with red dots and line, the CW output ability is extremely depending on the place of laser crystal as well as experimental end result coincides well with simulation end result. As a Notice, multimode Procedure happened in experiment in the event the measurement of your pump beam is greater than TEM00 cavity method and it results in greater CW output electricity in the displacement region beneath 3.5 mm.
... at fifty percent-top had been created in the grasp oscillator with selfsynchronization of the axial modes, explained inside our earlier posting. 21 The new version with the laser, in contrast to that explained inside our earlier report, made use of an Yb:KYW crystal with an N pcut (optical axis N p with the index ellipsoid was parallel towards the propagation route of your laser radiation), Using the polarization on the created radiation directed together the N m axis.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW because of the identical measurements of such chemical factors nearly one hundred% of Yb-doping can be attained.
When ytterbium-doped laser achieve media normally exhibit a little quantum defect, ytterbium-doped tungstates make it possible for for specially modest values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped about 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most effectively pumped around 981 nm.
This tandem of characteristics has far-reaching implications, specifically in the construction of compact still powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at place temperature were measured. The emission spectrum and lifetime of the 3 File four energized point out ended up decided. Employing common and modified Judd–Ofelt theories, the intensity parameters and the radiative lifetimes were being calculated and superior settlement Together with the experimental benefits was acquired for both theories.
