Applying our promoting offer, it is possible to display your emblem, further more beneath your products description, and these will been observed by quite a few photonics experts.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a exceptional substance that performs an essential purpose in laser technology. Its Major function is usually to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the pulse
The absorption and emission spectra of Yb:KYW Crystals display powerful peaks at 980 nm and 1030 nm, respectively, making certain successful Electrical power conversion and higher functionality in laser programs.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the similar dimensions of those chemical factors as much as a hundred% of Yb-doping may very well be reached. This distinctive attribute permits ytterbium to take the location of yttrium with pretty much no disruption on the crystal’s lattice.
The monoclinic crystal structures leads to a organic birefringence, helping to keep away from thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and therefore are used as lasing components to deliver ultrashort (~ a hundred-two hundred fs) substantial electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
5 mm in addition to the center of your beam caustic. In an effort to Verify the manner matching simulation, we performed KYW Crystal the experiment with Ng-Slice crystal oscillator, which was created Beforehand As well as in a exact ailment with simulation [eleven]. As proven in Determine 3(b) with purple dots and line, the CW output energy is extremely depending on the posture of laser crystal as well as the experimental final result coincides nicely with simulation end result. To be a note, multimode operation transpired in experiment if the sizing from the pump beam is greater than TEM00 cavity method and it will cause higher CW output energy while in the displacement area down below three.five mm.
For tungstates, the ytterbium doping concentration can be quite significant with no significant quenching because the replaced ions have an extremely equivalent ion radius, along with the inter-ion distance is fairly large.
... Don't just the posture of crystal within the cavity but additionally the amplification axis of crystal has an effect on the laser operation enormously, as the absorption and emission cross sections with the crystal are pretty unique according to the orientation in the crystal.
Although ytterbium-doped laser get media usually exhibit a little quantum defect, ytterbium-doped tungstates allow for for specifically tiny values. By way of example, a 1030-nm Yb:YAG laser would normally be pumped all-around 940 nm, whereas Yb:KGW or Yb:KYW can be most proficiently pumped around 981 nm.
Li2WO4-WO3 flux was productively used lessening The expansion temperature down below 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds for the P2/n House group.

Simultaneously, a shorter laser wavelength could be attained; it can be done to work using a quantum defect nicely under one%. Being a consequence, the heat era might be so smaller that this partly compensates the reduced thermal conductivity.
