The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is really a impressive material that plays a vital position in laser technology. Its Key functionality should be to create ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, on the other hand melt crystallization of high quality crystal is extremely hard as a consequence of section transition at ~920 oC. The very best seeded Remedy approach from
FIG. 4. Autocorrelation perform of the pulse 共a兲and spectrum 共b兲of the laser with a rectangular Lively aspect for an output electrical power of 700 mW. The width of
Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or a lot less, permit some time resolution required in laser-thrilled fluorescence lifetime spectroscopy and imaging tactics.Furthermore, they provide substantial pulse peak powers at significant repetition charges and reasonable regular output powers.
Just before the development of Nd:YAG, Nd3+:CaWO4 was an important exceptional-earth-doped laser acquire medium. It was in actual fact Utilized in the first continually functioning crystal laser.
Raman, luminescence and transmission spectra reveal optical features owing for the existence of thulium ions, and as a consequence the components may very well be further examined within the scope of laser and luminescence applications.

Having said that, after Nd3+:YAG turned commercially offered, the interest in CaWO4 dropped sharply. In later on years, specified other tungstate crystals began to appeal to loads of focus.
