The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, can be a impressive materials that performs an important job in laser engineering. Its Main functionality is to crank out ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the pulse
FIG. four. Autocorrelation operate of the heart beat 共a兲and spectrum 共b兲of the laser with a rectangular active component for an output electrical power of seven hundred mW. The width of
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW because of the similar dimensions of these chemical factors nearly a hundred% of Yb-doping could possibly be reached. This special characteristic permits ytterbium to take the spot of yttrium with just about no disruption into the crystal’s lattice.
Adhesion Take a look at Compliant with MIL-C-675C military requirements, an adhesion check involved implementing a tape that satisfies LT-90 specifications on to the lens movie layer. The tape was affixed completely after which taken off vertically. This treatment was carried out thrice, leading to no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical characteristics owing to your presence of thulium ions, and thus the supplies might be further examined while in the scope of laser and luminescence programs.

Li2WO4-WO3 flux was effectively utilized minimizing The expansion temperature underneath 900 oC. According to single crystal x-ray measurements, the crystal corresponds towards the P2/n Area group.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at place temperature were measured. The emission spectrum and lifetime on the three File four excited state have been decided. Applying regular and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes ended up calculated and very good arrangement Along with the experimental success was attained for both equally theories.
Right here you can submit thoughts and remarks. So far as they get approved because of the writer, they may appear previously mentioned this paragraph along with the creator’s answer. The author will choose acceptance based upon certain criteria. Primarily, The problem have to be of adequately broad curiosity.
