The get bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant in contrast with that of Yb:YAG. This allows for large wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values very well underneath 100 fs are achieved with passive mode locking.

Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the heart beat

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with direct longitudinal pumping by highly effective linear arrays of semiconductor injection lasers obtaining fiber output. To circumvent spectral narrowing during amplification as well as the corresponding lengthening from the amplified pulse when it's compressed, a mix of two Yb:KYW crystals were utilised, Together with the spectral maxima of your amplification shifted relative to each other and with spectral profiling of the amplified radiation.
Soon after air drying and subsequent cleaning that has a cotton cloth soaked in alcohol, the film area showed no signs of peeling or scratches.

Tungstates are inclined to acquire large Raman coefficients (�?Raman scattering). For that reason, they will make significant Raman gain at average optical intensities. It is achievable to utilize the laser crystal itself to be a Raman converter.

However, as soon as Nd3+:YAG became commercially obtainable, the fascination in CaWO4 dropped sharply. In later decades, particular other tungstate crystals began to bring in many awareness.
Though ytterbium-doped laser obtain media normally exhibit a little quantum defect, ytterbium-doped tungstates permit for especially little website values. For example, a 1030-nm Yb:YAG laser would Generally be pumped all around 940 nm, Whilst Yb:KGW or Yb:KYW could possibly be most efficiently pumped all over 981 nm.
This tandem of characteristics has considerably-achieving implications, significantly in the construction of compact nonetheless powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at space temperature ended up measured. The emission spectrum and life span in the three F 4 psyched point out were being determined. Making use of typical and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes were calculated and superior settlement Together with the experimental results was attained for the two theories.
