In useful terms, the Yb:KYW crystal has found its specialized niche in substantial-energy laser applications resulting from its ability to crank out higher Electrical power ultrashort laser pulses when preserving a compact measurement. The interaction of its characteristics �?seamless ytterbium substitution, strong absorption attributes, ultrashort pulse technology and efficiency in Vitality conversion �?positions the Yb:KYW crystal being a cornerstone inside the laser technological innovation, masking numerous fields starting from scientific investigate to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is often a extraordinary substance that plays a significant purpose in laser know-how. Its Main function is always to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat
In case you are aiming to obtain this site applying an anonymous Private/Proxy network, make sure you disable that and try accessing web-site once again.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the very similar sizes of those chemical elements approximately one hundred% of Yb-doping might be obtained. This special attribute permits ytterbium to take the area of yttrium with pretty much no disruption towards the crystal’s here lattice.
The monoclinic crystal structures ends in a purely natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to the equivalent sizes of these chemical factors as many as one hundred% of Yb-doping could possibly be reached.
Even though ytterbium-doped laser gain media frequently show a little quantum defect, ytterbium-doped tungstates enable for specifically modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, While Yb:KGW or Yb:KYW might be most effectively pumped all-around 981 nm.
This tandem of attributes has much-achieving implications, especially in the development of compact however powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at home temperature had been calculated. The emission spectrum and life span of your three F four excited point out have been established. Employing conventional and modified Judd–Ofelt theories, the depth parameters as well as the radiative lifetimes ended up calculated and excellent agreement While using the experimental outcomes was attained for each theories.
