The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is really a impressive substance that performs a very important job in laser technologies. Its Main operate will be to make ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in mild absorption at all over 981 nm makes the crystal like minded for diode pumping. It truly is further more Increased by its outstanding efficiency in this process, coupled with its small quantum defect.
FIG. four. Autocorrelation perform of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong active aspect for an output electrical power of seven hundred mW. The width of
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical aspects as many as a hundred% of Yb-doping can be accomplished. This special characteristic permits ytterbium to take the place of yttrium with virtually no disruption to the crystal’s lattice.
Before the development of Nd:YAG, Nd3+:CaWO4 was an important rare-earth-doped laser obtain medium. It had been in fact used in the primary consistently operating crystal laser.
FIG. one. Optical format of the laser with direct pumping While using the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output
Tungstates have a tendency to own superior Raman coefficients (�?Raman scattering). Therefore, they might produce substantial Raman obtain at moderate optical intensities. It is possible to use the laser crystal alone to be a Raman converter.
... at fifty percent-height were being produced within a master oscillator with selfsynchronization of your axial modes, described in our before write-up. 21 The new edition click here with the laser, unlike that explained in our previously write-up, made use of an Yb:KYW crystal by having an N pcut (optical axis N p from the index ellipsoid was parallel to your propagation path of your laser radiation), Along with the polarization from the produced radiation directed together the N m axis.
... Don't just the position of crystal within the cavity but additionally the amplification axis of crystal impacts the laser operation considerably, since the absorption and emission cross sections on the crystal are really distinct according to the orientation of the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, can be a impressive content that plays an important role in laser know-how. Its Principal perform would be to deliver ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
