The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a exceptional content that performs a vital position in laser technology. Its Most important purpose should be to produce ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
time. Crystals on the compound melts congruently at 1007 oC, however melt crystallization of top quality crystal is unachievable due to stage changeover at ~920 oC. The very best seeded Alternative approach from
When you are aiming to obtain This great site using an nameless Personal/Proxy network, you should disable that and try accessing website all over again.
Ultrafast lasers, with pulse widths of some picoseconds (10−twelve s) or significantly less, help time resolution required in laser-excited fluorescence life time spectroscopy and imaging methods.What's more, they provide superior pulse peak powers at substantial repetition rates and moderate ordinary output powers.
The monoclinic crystal structures brings about a organic birefringence, assisting to avoid thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical characteristics owing towards the existence of thulium ions, and for that reason the resources might be further get more info analyzed within the scope of laser and luminescence purposes.
Spatial framework from the beam plus the corresponding depth profiles I within the output of the laser.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of equivalent measurements of such chemical elements around one hundred% of Yb-doping can be accomplished.
Due to Formerly detected destructive habits which originated with the community you happen to be applying, remember to ask for unblock to web site.
This tandem of attributes has considerably-achieving implications, notably in the construction of compact nonetheless powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at place temperature had been calculated. The emission spectrum and lifetime of your 3 F 4 excited point out were being established. Using common and modified Judd–Ofelt theories, the depth parameters and also the radiative lifetimes were calculated and great arrangement with the experimental benefits was attained for each theories.
Talk to RP Photonics for any assistance regarding tungstate lasers, such as femtosecond lasers and substantial-power lasers.
