The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is often a remarkable materials that plays a crucial part in laser technological innovation. Its Key purpose will be to crank out ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the pulse
FIG. 4. Autocorrelation functionality of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular Energetic element for an output electric power of 700 mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of related sizes of these chemical factors approximately one hundred% of Yb-doping can be obtained. This unique attribute permits ytterbium to go ahead and take put of yttrium with pretty much no disruption into the crystal’s lattice.
The monoclinic crystal buildings brings about a pure birefringence, assisting to keep away from thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical features owing into the presence of thulium ions, and as a consequence the resources could be more examined within the scope of laser and luminescence applications.
Spatial construction from the beam and also the corresponding intensity profiles I for the output with the laser.

... Not just the placement of crystal from the cavity but will also the amplification axis of crystal has an effect on the laser Procedure considerably, since the absorption and emission cross sections on the crystal are very diverse based on the orientation of your crystal.
The thermal conductivity of prevalent double tungstates is in the get to 3–four W/(K m) �?which is not lousy in comparison with other laser crystals (although various occasions a lot less than for YAG), and pretty substantial compared Together with the thermal conductivity of usual glasses.
Li2WO4-WO3 flux was correctly applied lowering The expansion temperature down below 900 oC. In keeping with single crystal x-ray measurements, the crystal corresponds for check here the P2/n Place team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at room temperature have been calculated. The emission spectrum and life span of the 3 F 4 fired up state had been established. Employing standard and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes had been calculated and very good arrangement Together with the experimental effects was received for equally theories.
Simultaneously, a shorter laser wavelength may be attained; it is achievable to operate which has a quantum defect properly beneath one%. As being a consequence, the warmth generation is often so tiny this partly compensates the reduce thermal conductivity.
