99% and 96.07%, respectively. The 0% laser-induced harm threshold of Z-Lower in 1064 nm was about 40J/cm two , exceeding Substantially more than the applying requirement in certain higher ability laser methods. The polarization state of laser experienced minimal impact on the laser-induced problems features of I-form sample. Then the laser-induced hurt morphologies of 98% DKDP crystals induced by the 1064 nm and 532 nm lasers were being investigated. The final results indicated which the "micro-explosion" of different kinds of defects in the majority triggered various problems morphologies, and a lot of cracks from the harm pinpoints introduced the typical orientation with far better regularity in see of your I-sort period-match path. Our research can provide a reference to the purposes of highly deuterated DKDP crystals in substantial power laser methods.
e., potassium or hydrogen) nearby. Crystals made up of both of those the 270-nm absorption band plus the Fe3+ EPR spectra ended up X-ray irradiated at room temperature then subjected to the series of thermal anneals as much as a hundred and fifty°C. These treatment options brought about modifications in equally the absorption band plus the EPR spectra, even so the behaviors with the optical and EPR options didn't correlate. This may be stated if a percentage of the Fe ions occupy a web page in the KDP crystals aside from the K+ web-site. We advise that most of the optical absorption in the two hundred-to-300nm region is due to Fe ions substituting for phosphorus; i.e., (FeO4)2�?molecular models are current while in the KDP crystals and give rise to ultraviolet absorption.
Additional attempts are actually paid out during the processes of purity of Uncooked materials, ongoing filtration engineering, thermal annealing and laser conditioning for increasing the laser-induced harm threshold (LIDT) and these processes empower the at the moment developed crystals to meet the specs on the laser technique for inertial confinement fusion (ICF), Even though the laser problems system and laser conditioning system remain not well understood. The progress on advancement of huge-aperture high-high quality DKDP crystal would assistance the development of ICF in China.
Investigation of bulk laser problems in KDP crystal as a perform of laser irradiation route, polarization, and wavelength
Meanwhile, to make sure continued assistance, we are exhibiting the location devoid of kinds and JavaScript.
The deuterium homogeneities of huge-measurement DKDP crystals developed by common growth technique and swift growth technique had been investigated in situ by Raman spectroscopy, respectively37,53. The outcome indicated the inhomogeneity of deuterium articles was approximated to generally be 0.
The impurities with ion condition in the answer could be absorbed within the rising area and modify the movement of the growth ways, the growth behavior, and also the crystallinity of DKDP crystals.

The polarized Raman spectra of deuterated potassium dihydrogen phosphate crystals with unique deuterium concentrations are measured. Together with the increasing deuterium concentration, the Raman peaks which happen to be assigned as the internal vibrations with the (H/D)2PO−four anion shift to decreased wavenumbers. This red-shift contributes to the reduce from the bonding drive from the P—O bond because of website the substitution of deuterium for hydrogen.
