The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is often a impressive substance that performs a significant purpose in laser technological know-how. Its Most important purpose will be to produce ultrashort pulses of light, spanning just some hundred femtoseconds.

Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with immediate longitudinal pumping by impressive linear arrays of semiconductor injection lasers owning fiber output. To forestall spectral narrowing through amplification plus the corresponding lengthening of the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals had been used, While using the spectral maxima on the amplification shifted relative to one another and with spectral profiling from the amplified radiation.

Just after air drying and subsequent cleaning which has a cotton cloth soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.

Superior-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications

While ytterbium-doped laser get media commonly exhibit a small quantum defect, ytterbium-doped tungstates enable for especially modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped close to 940 nm, While Yb:KGW or Yb:KYW can be most effectively pumped around 981 nm.

This tandem of characteristics has considerably-reaching implications, specifically in the construction of compact nevertheless powerfull lasers.
