Optical elements made of KDP, DKDP crystals (Pockels elements, frequency conversion elements, phaseplates) are up to now among the most expensive and significant ones in high-power laser systems with frequency conversion into higher harmonics. Only some companies have mastered such production technology of optical elements with the aperture size up to 40x40 cm. The production is characterized by very long cycles of crystal growth and large waste at manufacturing opticai elements, which leads to an extremely high price ofthe products. An alternative technology based on rapid technology of profiled growth of crystal products and the technology of optical diamond micromilling by means of ISM-600 machines are developed now at the Institute of Applied Physics RAS. The cycle duration of the crystal product growth reduces tens times, cuffing of the grown product mto optical elements proves to be practically wasteless This leads to reduction ofproduct cost and significant shortenmg ofproduct cycle duration The quality of crystal growth and optical processing is consistent with the requirements of optical systems. This together with the described applied technologies has permitted to manufacture optical elements for a series ofhighpower lasers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
