The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a impressive materials that plays a significant job in laser technologies. Its primary perform is always to make ultrashort pulses of light, spanning just some hundred femtoseconds.

The Yb:KYW crystal’s proficiency in light-weight absorption at about 981 nm would make the crystal well matched for diode pumping. It can be additional Increased by its amazing performance in this method, coupled with its small quantum defect.

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing for the duration of amplification along with the corresponding lengthening in the amplified pulse when it's compressed, a mix of two Yb:KYW crystals ended up utilized, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling of your amplified radiation.

Just before the development of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser get medium. It was in truth used in the primary continuously working crystal laser.

... at fifty percent-height were created in a very grasp oscillator with selfsynchronization from the axial modes, explained within our earlier article. 21 The new edition in the laser, in contrast to that explained inside our before posting, applied an Yb:KYW crystal using an N pcut (optical more info axis N p of the index ellipsoid was parallel to your propagation path of your laser radiation), Together with the polarization of the produced radiation directed together the N m axis.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the comparable dimensions of those chemical factors up to a hundred% of Yb-doping may be attained.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is a outstanding material that performs an important purpose in laser technological know-how. Its Most important purpose is usually to create ultrashort pulses of light, spanning just a couple hundred femtoseconds.

Question RP Photonics for any information relating to tungstate lasers, which includes femtosecond lasers and high-electric power lasers.
