In realistic conditions, the Yb:KYW crystal has located its specialized niche in superior-energy laser applications because of its ability to deliver superior Electricity ultrashort laser pulses even though keeping a compact sizing. The interplay of its functions �?seamless ytterbium substitution, sturdy absorption features, ultrashort pulse technology and efficiency in Power conversion �?positions the Yb:KYW crystal being a cornerstone within the laser know-how, covering various fields ranging from scientific analysis to industrial applications.
It is a preview of membership material, log in by using an institution to examine access. Obtain this informative article
time. Crystals of your compound melts congruently at 1007 oC, having said that melt crystallization of top quality crystal is not possible on account of section transition at ~920 oC. The best seeded solution method from
The absorption and emission spectra of Yb:KYW Crystals display solid peaks at 980 nm and 1030 nm, respectively, ensuring effective Vitality conversion and higher performance in laser programs.
Optical format of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output on the radiation, WP can be a fifty percent-wave plate, CL is actually a collimating lens, FL is really a focusing lens, AE is definitely an Lively factor comprised of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC could be the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
The monoclinic crystal constructions leads to a pure birefringence, assisting to steer clear of thermally induced polarization rotation and depolarization decline.

5 mm in addition to the middle on the beam caustic. As a way to Check out the method matching simulation, we carried out the experiment with Ng-Lower crystal oscillator, which was produced Formerly As well as in a identical condition with simulation [eleven]. As demonstrated in Determine three(b) with pink dots and line, the CW output energy is extremely dependent on the position of laser crystal and also the experimental end result coincides perfectly with simulation consequence. As being a note, multimode operation occurred in experiment if the dimension from the pump beam is larger sized than TEM00 cavity method and it triggers increased CW output power during the displacement location beneath 3.5 mm.
For tungstates, the ytterbium doping focus can be extremely high with no substantial quenching as the replaced ions have a really identical ion radius, as well as the inter-ion length is pretty substantial.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical aspects as much as a hundred% of Yb-doping may be attained.
