The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is often a outstanding content that plays a vital purpose in laser technological know-how. Its primary function is to generate ultrashort pulses of light, spanning just a few hundred femtoseconds.
The Yb:KYW crystal’s proficiency in gentle absorption at all-around 981 nm tends to make the crystal well matched for diode pumping. It really is even further Increased by its outstanding effectiveness in this process, coupled with its small quantum defect.

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing throughout amplification and the corresponding lengthening of your amplified pulse when it can be compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima from the amplification shifted relative to each other and with spectral profiling of your amplified radiation.
Immediately after air drying and subsequent cleaning that has a cotton cloth soaked in Liquor, the movie floor confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are made use of as lasing products to crank out ultrashort (~ one hundred-two hundred fs) significant electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.
Tungstates are likely to have higher Raman coefficients (�?Raman scattering). For that reason, they might generate significant Raman gain at moderate optical intensities. It is possible to use the laser crystal itself like a Raman converter.
For tungstates, the ytterbium doping focus can be quite substantial with out significant quenching because the changed ions have an incredibly equivalent ion radius, plus the inter-ion length is relatively substantial.
High-electricity repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
When ytterbium-doped laser attain media frequently show a little quantum defect, ytterbium-doped tungstates allow for for particularly little values. As an example, a 1030-nm Yb:YAG laser would Typically be pumped close to 940 nm, whereas Yb:KGW or Yb:KYW could be most competently pumped close to 981 nm.
This tandem of attributes has significantly-achieving implications, especially in the development of compact yet read more powerfull lasers.

At the same time, a shorter laser wavelength can be attained; it is feasible to operate that has a quantum defect properly below one%. As being a consequence, the warmth generation is often so tiny this partly compensates the reduce thermal conductivity.
