In useful phrases, the Yb:KYW crystal has observed its market in substantial-energy laser apps resulting from its capability to produce high Electrical power ultrashort laser pulses when keeping a compact size. The interplay of its capabilities �?seamless ytterbium substitution, robust absorption attributes, ultrashort pulse era and performance in Power conversion �?positions the Yb:KYW crystal as being a cornerstone inside the laser know-how, covering diverse fields starting from scientific investigate to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, can be a impressive substance that performs an important job in laser technological innovation. Its Major function is usually to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in mild absorption at all over 981 nm tends to make the crystal well suited for diode pumping. It can be additional enhanced by its impressive performance in this method, coupled with its very low quantum defect.
Colour-coded reflectivity of the Bragg mirror for a function of wavelength and angle on the incident beam.
Ultrafast lasers, with pulse widths of some picoseconds (ten−12 s) or considerably less, enable enough time resolution expected in laser-psyched fluorescence life span spectroscopy and imaging techniques.Furthermore, they provide large pulse peak powers at large repetition rates and average ordinary output powers.
Just before the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It absolutely was the truth is Employed in the first repeatedly operating crystal laser.

... Not simply the posture of crystal within the cavity but additionally the amplification axis of crystal impacts the laser Procedure considerably, because the absorption and emission cross sections from the crystal are really distinctive in accordance with the orientation on the crystal.
When ytterbium-doped laser gain media typically exhibit a small quantum defect, ytterbium-doped tungstates make it possible for for significantly small values. One example is, a 1030-nm Yb:YAG laser would Typically be pumped all around 940 nm, While Yb:KGW or Yb:KYW may very well be most competently pumped around 981 nm.
