It was revealed that, by advantage of the reduced dispersion of the team velocity, the KDP crystal has some strengths more than silica: a larger pulse compression coefficient, Primarily at a little value of the В -integral ( B = 5, �? 9), decreased complete values of chirped mirror dispersion, as well as a likelihood to regulate the magnitude of nonlinearity and dispersion by transforming crystal orientation.
Consequently, the injury mechanism is very complicated, and it is urgent to grasp the laser induced hurt system of KDP-household crystals. In this particular paper, the cooperated exploration of Shanghai Institute of Optics and Mechanics with Fujian Institute of Analysis to the Construction of Matter, Shandong College along with other crystal study institutes is reviewed. The laser induced hurt Homes of KDP and DKDP crystals utilized as optical switching, frequency doubling and frequency mixing optical features have been investigated. The optimization of crystal growth method as well as control of essential variables were being guided and the prevailing troubles and alternatives were prospected. The analysis has reference value for the event of large efficiency KDP-family members crystals as well as their rational application in substantial-ability laser systems.
The adjust of the whole depolarized reduction with the transmission aperture in the event the incident beam ability is 1kW.
Then the effects of neutron diffraction had been accustomed to calibrate the relationship between the deuterium information plus the variation of PO4 vibration peak in Raman spectra as well as absorption bands in IR spectra, respectively. In accordance with the Raman shifts of PO4 vibration peak of KDP and DKDP crystals with various degrees of deuteration (Fig.

the equivalent potential of your PPC (CPC) improves to 240pF as well as voltage applied on the
DKDP box is usually employed for four hundred~1100nm Q-switched programs.Most lamp-pumped Nd:YAG lasers,ruby lasers,and low repetition fee DPSS lasers that you can buy use DKDP Q-switched switches employing DKDP bins。
high typical electric power software, it is necessary to utilize two items of similar crystal to
By reformative structure and using a capacity to share the gasoline discharge voltage, the DKDP PPC driven by one pulse is understood. As fuel breakdown hold off time is stable, and discharge plasma is uniformly loaded the entire aperture, it satisfies the demand from customers of plasma electrode for that repetition-charge PPC with DKDP crystal. The switch performance of PPC at The entire aperture is a lot better than ninety nine%.
parametric amplification stage by chirped pulses of idler radiation using a wavelength of 1250 nm. The saturated achieve of the
Nonlinear deuterated potassium dihydrogen phosphate (DKDP) and KDP crystals can be utilized for a range of programs because of their massive nonlinear optical and electro-optical coefficients.
The effects display that the whole signal produced via the pump beam is definitely the sum of the signals produced by the two parts which have polarization parallel and orthogonal towards the optic axis. The peak signal intensity, which is of significance for prime-electric power laser apps, is dependent upon the orientation of the optic axis and can vary by an element of about 2. The excellent settlement amongst experimental data and modeling success validates the involved styles and allows a single to take into account ideal crystal Reduce designs for unique applications.
789 �?sixteen.53x. In the meantime, the stability of FHG was enormously improved, as well as angular array of effectiveness steadiness was elevated to 4.four moments in utmost. This do the job not merely systematically demonstrates the FHG traits of KDP-household crystals, which supplies a fantastic reference for that deep ultraviolet laser era, but also offers a new way to evaluate The fundamental parameters of nonlinear more info optical resources.
The neutron scattering duration on the deuterium atom is more substantial than that of other atoms in DKDP crystal, so neutron diffraction can be utilized as an effective technique to right figure out the deuterium information of DKDP crystals50,51.
