The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is actually a exceptional material that performs a vital part in laser technologies. Its Principal perform is to crank out ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the heartbeat
FIG. 4. Autocorrelation functionality of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular Energetic ingredient for an output ability of seven hundred mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the related measurements of those chemical things up to one hundred% of Yb-doping can be achieved. This distinctive characteristic permits ytterbium to go ahead and take place of yttrium with practically no disruption towards the crystal’s lattice.
The monoclinic crystal constructions leads to a organic birefringence, helping to stay away from thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra reveal optical capabilities owing towards the existence of thulium ions, and as a consequence the supplies may be even more studied within the scope of laser and luminescence applications.
