The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is often a extraordinary material that performs an important function in laser engineering. Its Most important functionality is to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the pulse

The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing economical energy conversion and high efficiency in laser techniques.

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by highly effective linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification as well as the corresponding lengthening from the amplified pulse when it is compressed, a mix of two Yb:KYW crystals were being utilised, With all the spectral maxima of the amplification shifted relative to one another and with spectral profiling from the amplified radiation.

The monoclinic crystal buildings ends in a normal birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are applied as lasing resources to create ultrashort (~ 100-200 fs) high electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.

Tungstates have a tendency to own superior Raman coefficients (�?Raman scattering). Consequently, they could crank out major Raman gain at moderate optical intensities. It is possible to utilize the laser crystal alone for a Raman converter.

... at fifty percent-height were created in a very learn oscillator with selfsynchronization with the axial modes, described in our before report. 21 The new version of your laser, contrary to that described inside our earlier posting, utilised an Yb:KYW crystal with the N pcut (optical axis N p of your 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.

... Don't just the position of crystal inside the cavity but in addition the amplification axis of crystal influences the laser operation tremendously, because the absorption and emission cross sections with the crystal are pretty distinctive in accordance with the orientation with the crystal.
