simplified to be a variation capacity CPC. C0 is usually a higher voltage capability, Z may be the resistance from the
a Deuterium distribution in DKDP crystals developed from methods with various deuterium contents and supersaturation levels ranging from 0.
The nonlinearity of such crystals is fairly low, these crystals might be developed in big dimensions. They uncovered their software as nonlinear frequency doublers, triplers, and quandruplers of Nd-doped lasers and as Q-switch products for Ti:Sapphire, Alexandrite, Nd-doped lasers. The primary drawback is always that these crystals are really hygroscopic, as a result sealed housing and dry running disorders ought to be ensured.
99% and 96.07%, respectively. The 0% laser-induced harm threshold of Z-Slash in 1064 nm was about 40J/cm two , exceeding A great deal a lot more than the application requirement in selected superior power laser systems. The polarization state of laser experienced minimal effect on the laser-induced damage attributes of I-type sample. Then the laser-induced harm morphologies of ninety eight% DKDP crystals induced from the 1064 nm and 532 nm lasers have been investigated. The outcome indicated that the "micro-explosion" of various forms of defects in the majority brought about different damage morphologies, and lots of cracks in the problems pinpoints introduced the normal orientation with improved regularity in look at from the I-sort stage-match path. Our study can offer a reference for that applications of highly deuterated DKDP crystals in substantial power laser techniques.
Suppression of transverse stimulated Raman scattering with laser-induced problems array in a substantial-aperture potassium dihydrogen phosphate crystal
In typical electricity lasers, the repetition-level Pockels mobile more info is normally made use of as isolators and Q-
The IR outcomes illustrate that two linear interactions existed among the deuteration level as well as relative variants in the spectra. The two spectroscopic techniques is usually merged and used to measure the degree of deuteration while in the crystals of DKDP developed from solutions with deuteration amount of below ninety two%. ATR-IR spectroscopy is a lot more appropriate for measuring extremely deuterated DKDP crystals.
By reformative style and design and using a capacity to share the gas discharge voltage, the DKDP PPC pushed by 1 pulse is understood. As gas breakdown hold off time is stable, and discharge plasma is uniformly crammed the full aperture, it fulfills the need of plasma electrode for your repetition-rate PPC with DKDP crystal. The switch performance of PPC at The entire aperture is better than 99%.
Elements such as mechanical deformation and temperature improvements cause section mismatch in optical parametric amplification systems, impacting Strength steadiness. A section payment process by means of the linear electro-optic outcome can triumph over this limitation. Period mismatch compensation traits were simulated by using the linear electro-optic influence in 70%-deuterated DKDP and ninety five%-deuterated DKDP. This process was placed on OPA programs to confirm its feasibility.
The impurities with ion state in the answer could possibly be absorbed on the expanding surface and modify the movement of The expansion methods, The expansion practice, as well as the crystallinity of DKDP crystals.

The residual stresses not simply have an impact on the mechanical properties in the crystal and also have an affect on one other Attributes. Thus, it is vital to analyze the residual tension in DKDP crystal for its programs in substantial ability laser systems.
