The Single Best Strategy To Use For KYW Crystal

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is rather substantial in contrast with that of Yb:YAG. This enables for vast wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values effectively beneath 100 fs have been obtained with passive manner locking.

The Yb:KYW crystal’s proficiency in gentle absorption at about 981 nm will make the crystal compatible for diode pumping. It is more enhanced by its exceptional efficiency in this method, coupled with its minimal quantum defect.

Colour-coded reflectivity of the Bragg mirror for a perform of wavelength and angle of the incident beam.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the identical dimensions of these chemical components as many as a hundred% of Yb-doping might be realized. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with virtually no disruption towards the crystal’s lattice.

Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It had been in fact used in the primary consistently operating crystal laser.

5 mm besides the center with the beam caustic. As a way to check the method matching simulation, we executed the experiment with Ng-Minimize crystal oscillator, which was developed Earlier As well as in a identical affliction with simulation [eleven]. As proven in Determine three(b) with crimson dots and line, the CW output ability is highly depending on the posture of laser crystal as well as the experimental final result coincides nicely with simulation end result. As a Be aware, multimode Procedure happened in experiment when the dimension with the pump beam is larger than TEM00 cavity mode and it brings about bigger CW output energy inside the displacement area down click here below three.five mm.

... at 50 %-height ended up generated within a learn oscillator with selfsynchronization from the axial modes, explained in our previously short article. 21 The new version in the laser, compared with that described in our previously posting, utilized an Yb:KYW crystal using an N pcut (optical axis N p of your index ellipsoid was parallel towards the propagation route with the laser radiation), with the polarization in the produced radiation directed alongside the N m axis.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the identical sizes of such chemical aspects approximately 100% of Yb-doping could be obtained.

Whilst ytterbium-doped laser get media usually show a little quantum defect, ytterbium-doped tungstates allow for for specifically compact values. By way of example, a 1030-nm Yb:YAG laser would normally be pumped close to 940 nm, Whilst Yb:KGW or Yb:KYW might be most successfully pumped all around 981 nm.

Li2WO4-WO3 flux was productively utilized minimizing the growth temperature beneath 900 oC. As outlined by solitary crystal x-ray measurements, the crystal corresponds on the P2/n House group.
