In practical conditions, the Yb:KYW crystal has discovered its market in superior-electric power laser applications as a consequence of its capability to generate high energy ultrashort laser pulses when retaining a compact dimension. The interaction of its features �?seamless ytterbium substitution, powerful absorption features, ultrashort pulse technology and efficiency in Strength conversion �?positions the Yb:KYW crystal to be a cornerstone within the laser technological know-how, masking various fields ranging from scientific investigation to industrial purposes.
The comparison with Eyeglasses is appropriate since the large attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing inside of 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 productive Electricity conversion and superior performance in laser units.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the comparable measurements of those chemical things up to one hundred% of Yb-doping may be achieved. This exclusive attribute permits ytterbium to take the spot of yttrium with pretty much no disruption on the crystal’s lattice.
The monoclinic crystal buildings ends in a pure birefringence, helping to avoid thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical options owing towards the existence of thulium ions, and therefore the supplies could possibly be even further analyzed during the scope of laser and luminescence applications.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a dual-crystal Yb:KGW laser
... at fifty percent-top were being produced within a master oscillator with selfsynchronization of the axial modes, explained within our earlier posting. 21 The new version from the laser, unlike that explained in our earlier short article, utilised an Yb:KYW crystal with the N pcut (optical axis N p of your index ellipsoid was parallel towards the propagation direction with the laser radiation), With all the polarization of your produced radiation directed together the N m more info axis.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of comparable dimensions of those chemical factors as much as a hundred% of Yb-doping may very well be attained.
When ytterbium-doped laser gain media usually show a little quantum defect, ytterbium-doped tungstates allow for particularly little values. For instance, a 1030-nm Yb:YAG laser would Typically be pumped close to 940 nm, whereas Yb:KGW or Yb:KYW could be most efficiently pumped around 981 nm.
This tandem of attributes has much-reaching implications, significantly in the construction of compact nonetheless powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at area temperature have been measured. The emission spectrum and life span of your 3 File four thrilled condition ended up identified. Using regular and modified Judd–Ofelt theories, the intensity parameters as well as the radiative lifetimes have been calculated and fantastic arrangement Along with the experimental success was attained for both theories.
At the same time, a shorter laser wavelength is usually received; it is possible to work using a quantum defect nicely down below 1%. As a consequence, the warmth technology might be so little this partly compensates the lower thermal conductivity.
