In sensible phrases, the Yb:KYW crystal has found its niche in large-electrical power laser applications because of its power to crank out substantial Vitality ultrashort laser pulses even though retaining a compact dimension. The interaction of its options �?seamless ytterbium substitution, sturdy absorption features, ultrashort pulse technology and effectiveness in Strength conversion �?positions the Yb:KYW crystal being a cornerstone inside the laser know-how, covering various fields ranging from scientific investigate to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, can be a remarkable materials that performs a vital position in laser technology. Its Key perform should be to create ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at all-around 981 nm helps make the crystal compatible for diode pumping. It's even more enhanced by its amazing effectiveness in this process, coupled with its small quantum defect.

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers possessing fiber output. To prevent spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals were being employed, With all the spectral maxima of your amplification shifted relative to each other and with spectral profiling from the amplified radiation.
Right after air drying and subsequent cleaning which has a cotton fabric soaked in alcohol, the movie surface confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing components to generate ultrashort (~ 100-200 fs) higher electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
Spatial structure in the beam plus the corresponding depth profiles I in the output of your laser.

... Not merely the place of crystal from the cavity but will also the amplification axis of crystal influences the laser Procedure drastically, since the absorption and emission cross sections of the crystal are pretty different according to the orientation of the crystal.
Even though ytterbium-doped laser gain media usually exhibit a little quantum defect, ytterbium-doped tungstates let for specifically modest values. As an example, a 1030-nm Yb:YAG laser would Ordinarily be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most efficiently pumped about 981 nm.
Li2WO4-WO3 get more info flux was productively applied cutting down the growth temperature below 900 oC. According to single crystal x-ray measurements, the crystal corresponds to your P2/n Room group.
