We summarize new investigations in the density and morphology of bulk damage in KDP crystals being a operate of pulse length, temporal profile, wavelength, and energy fluence. As Formerly claimed by Runkel et al.1, we also learn that the size of bulk hurt web pages differs approximately linearly with pulse length for pulses among one ns and 9 ns. Even so this development no longer applies at pulse durations down below 1 ns. Experiments measuring the hurt density and measurement distribution to be a functionality of wavelength validate quite a few prior performs which indicated a solid dependence of injury density with wavelength. However, we also realize that the size of harm web-sites is fairly insensitive to wavelength.

Fig. 2. The modify of the total depolarized loss at the transmission aperture when the incident

The alter of the overall depolarized reduction on the transmission aperture once the incident beam energy is 1kW.

For comparison, monoclinic DKDP crystals were developed from your similar Option. Surface morphologies of tetragonal and monoclinic DKDP crystals had been investigated by AFM procedure. The various progress patterns in between tetragonal and monoclinic DKDP crystals had been analyzed As outlined by their crystal constructions with bond valence model.

99% and 96.07%, respectively. The 0% laser-induced hurt threshold of Z-Slice in 1064 nm was about 40J/cm two , exceeding much greater than the application requirement in particular large electricity laser programs. The polarization state of laser experienced tiny effect on the laser-induced destruction properties of I-sort sample. Then the laser-induced injury morphologies of ninety eight% DKDP crystals induced from the 1064 nm and 532 nm lasers were investigated. The results indicated which the "micro-explosion" of different forms of defects in the bulk triggered diverse problems morphologies, and plenty of cracks in the destruction pinpoints offered the regular orientation with superior regularity in check out of the I-form stage-match way. Our exploration can provide a reference for that applications of hugely deuterated DKDP crystals in high electric power laser techniques.

In normal energy lasers, the repetition-amount Pockels cell will likely be utilized as isolators and Q-

Electro-optic coefficient measurement of the K(H1−xD x )2PO4 crystal based upon χ nonlinear optical know-how

Matters may be refined even more during the search engine results. The subject side will reveal the higher-stage subjects connected to the articles or blog posts returned from the search engine results. Specific COLLECTIONS

789 �?16.53x. Meanwhile, The soundness of FHG was enormously enhanced, and also the angular array of efficiency stability was improved to 4.4 occasions in highest. This operate not merely systematically demonstrates the FHG features of KDP-relatives crystals, which delivers a superb reference for that deep ultraviolet laser era, but also offers a brand new solution to evaluate The fundamental parameters of nonlinear optical supplies.

The neutron scattering size from the deuterium atom is larger than that of other atoms in DKDP crystal, so neutron diffraction can be employed as a highly effective technique to immediately determine the deuterium information of DKDP crystals50,fifty one.
