In simple conditions, the Yb:KYW crystal has discovered its market in substantial-electric power laser purposes because of its capability to crank out superior Electrical power ultrashort laser pulses whilst preserving a compact measurement. The interaction of its capabilities �?seamless ytterbium substitution, solid absorption features, ultrashort pulse era and efficiency in energy conversion �?positions the Yb:KYW crystal to be a cornerstone from the laser technological innovation, covering diverse fields starting from scientific study to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is really a exceptional substance that performs a crucial purpose in laser technology. Its Main operate is to create ultrashort pulses of light, spanning only a few hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, nonetheless soften crystallization of top quality crystal is not possible due to stage changeover at ~920 oC. The top seeded Resolution strategy from
The absorption and emission spectra of Yb:KYW Crystals Display screen sturdy peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and superior efficiency in laser techniques.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to identical dimensions of such chemical elements around one hundred% of Yb-doping may be reached. This exclusive characteristic permits ytterbium to take the location of yttrium with just about no disruption on the crystal’s lattice.
Just after air drying and subsequent cleaning by using a cotton cloth soaked in alcohol, the movie surface area showed no signs of peeling or scratches.
FIG. one. Optical format of the laser with direct pumping with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output
Tungstates have a tendency to get large Raman coefficients (�?Raman scattering). As a result, they will make substantial Raman get at moderate optical intensities. It is feasible to use the laser crystal alone for a Raman converter.
EKSMA Optics makes use of cookies to supply you with the best buying encounter. If you go on to use our companies, we will assume that you simply agree to the use of this kind of cookies.
... Not simply the posture of crystal while in the cavity but in addition the amplification axis of crystal has an effect on the laser operation enormously, because the absorption and emission cross sections of the crystal are very different according to the orientation of your crystal.
The thermal conductivity of prevalent double tungstates is with the get to 3–four W/(K m) �?which is not poor in contrast with other laser crystals (although several moments less than for YAG), and pretty massive in comparison With all the thermal conductivity of standard glasses.
