The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is really a extraordinary content that plays a very important purpose in laser technologies. Its Key function will be to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heart beat
FIG. four. Autocorrelation functionality of the heart beat 共a兲and spectrum 共b兲of a laser with a rectangular Lively element for an output energy of seven hundred mW. The width of
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of very similar dimensions of such chemical elements as much as a hundred% of Yb-doping could be accomplished. This special characteristic permits ytterbium to go ahead and take put of yttrium with virtually no disruption to the crystal’s lattice.
Adhesion Examination Compliant with MIL-C-675C military services requirements, an adhesion examination included implementing a tape that satisfies LT-ninety technical specs onto the lens film layer. The tape was affixed completely then taken off vertically. This course of action was executed thrice, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical characteristics owing to the presence of thulium ions, and as a consequence the supplies can be further researched during the scope of laser and luminescence applications.
Spatial framework on the beam and the corresponding intensity profiles I on the output of your laser.
For tungstates, the ytterbium doping focus can be extremely higher devoid of considerable quenching because the replaced ions have a really comparable ion radius, and the inter-ion length is pretty massive.
High-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
Whilst ytterbium-doped laser obtain media normally show a small quantum defect, ytterbium-doped tungstates let for significantly small values. For instance, a 1030-nm Yb:YAG laser would Typically be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most efficiently pumped all-around 981 nm.
