The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a amazing product that plays a vital role in laser engineering. Its Principal operate will be to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at all over 981 nm tends to make the crystal like minded for diode pumping. It can be further more enhanced by its outstanding efficiency in this process, coupled with its reduced quantum defect.

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers having fiber output. To prevent spectral narrowing throughout amplification and also the corresponding lengthening of the amplified pulse when it is compressed, a combination of two Yb:KYW crystals were made use of, Together with the spectral maxima in the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
After air drying and subsequent cleaning using a cotton fabric soaked in Liquor, the movie surface showed no indications of peeling or scratches.
Raman, luminescence and transmission spectra reveal optical functions owing on the presence of thulium ions, and for that reason the elements might be even more analyzed during the scope of laser and luminescence purposes.
Tungstates tend to get significant Raman coefficients (�?Raman scattering). Therefore, they are able to make major Raman acquire at moderate optical intensities. It is feasible to use the laser crystal by itself being a Raman converter.
For tungstates, the ytterbium doping focus can be very significant with out major quenching as the replaced ions have click here an incredibly identical ion radius, and also the inter-ion distance is fairly substantial.
Large-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is a extraordinary product that performs a vital part in laser engineering. Its Main function should be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
