The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, can be a amazing material that performs a very important function in laser technological innovation. Its Key functionality is to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of very similar dimensions of these chemical features approximately one hundred% of Yb-doping can be achieved. This distinctive characteristic permits ytterbium to take the position of yttrium with pretty much no disruption into the crystal’s lattice.
The monoclinic crystal structures brings about a natural birefringence, helping to keep away from thermally induced polarization rotation and depolarization reduction.

On the other hand, as soon as Nd3+:YAG grew to become commercially offered, the desire in CaWO4 dropped sharply. In afterwards many years, specified other tungstate crystals began to catch the attention of lots of focus.
While ytterbium-doped laser acquire media typically exhibit a small quantum defect, ytterbium-doped tungstates let for specially modest values. Such as, a 1030-nm Yb:YAG laser would normally be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most competently pumped all-around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is usually a extraordinary product that plays an important role in laser technologies. Its Main function should be to crank out ultrashort pulses more info of light, spanning just a few hundred femtoseconds.
