In useful conditions, the Yb:KYW crystal has observed its market in high-electric power laser programs on account of its capacity to make high Strength ultrashort laser pulses while retaining a compact dimensions. The interaction of its options �?seamless ytterbium substitution, solid absorption qualities, ultrashort pulse technology and efficiency in Power conversion �?positions the Yb:KYW crystal to be a cornerstone within the laser technologies, masking varied fields starting from scientific investigation to industrial programs.

time. Crystals in the compound melts congruently at 1007 oC, however melt crystallization of top quality crystal is impossible due to section transition at ~920 oC. The highest seeded Answer system from
FIG. four. Autocorrelation function of the heartbeat 共a兲and spectrum 共b兲of a laser with an oblong Lively component for an output electricity of seven-hundred mW. The width of
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the identical dimensions of these chemical elements up to a hundred% of Yb-doping may very well be achieved. This one of a kind attribute permits ytterbium to take the location of yttrium with almost no disruption into the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C navy expectations, an adhesion examination concerned applying a tape that satisfies LT-90 specs on to the lens movie layer. The tape was affixed entirely after which removed vertically. This procedure was done three times, leading to no blistering or peeling.
Raman, luminescence and transmission spectra expose optical characteristics owing into the presence of thulium ions, and as a consequence the supplies can be even further studied while in the scope of laser and luminescence applications.
5 mm other than the middle from the beam caustic. So that you can Verify the mode matching simulation, we carried out the experiment read more with Ng-Slash crystal oscillator, which was created Earlier As well as in a identical ailment with simulation [eleven]. As demonstrated in Figure 3(b) with crimson dots and line, the CW output electric power is very depending on the situation of laser crystal and also the experimental end result coincides nicely with simulation end result. Being a Notice, multimode operation happened in experiment in the event the dimension on the pump beam is much larger than TEM00 cavity mode and it leads to higher CW output electric power while in the displacement region down below 3.five mm.
For tungstates, the ytterbium doping focus can be extremely significant devoid of important quenching since the replaced ions have an extremely very similar ion radius, and also the inter-ion length is fairly massive.
Significant-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
While ytterbium-doped laser obtain media normally exhibit a small quantum defect, ytterbium-doped tungstates allow for especially compact values. One example is, a 1030-nm Yb:YAG laser would normally be pumped all over 940 nm, Whilst Yb:KGW or Yb:KYW might be most proficiently pumped close to 981 nm.
Li2WO4-WO3 flux was correctly utilized reducing the growth temperature under 900 oC. In accordance with one crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a extraordinary content that plays an important job in laser technological know-how. Its Major function should be to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
