This chapter presents a survey oλ recent achievements oλ the ITMO University (St. Petersburμ, Russia) in developinμ new holoμraphic media such as luoride, chloride, and bromide silicate photo-thermo-reλractive (PTR) μlasses as well as the holoμraphic difractive optical elements that are the volume "raμμ μratinμs recorded in the μlasses λor improvinμ dramatically the parameters oλ laser systems oλ diferent types. The photo-thermo-induced crystallization process and the properties oλ luoride, chloride, and bromide PTR μlasses are demonstrated. This new technoloμy enabled recordinμ hiμh-eiciency phase volume holoμrams in the optical quality silicate μlass. These holoμrams are used λor developinμ a number oλ unique difractive optical elements that provide new opportunities λor the laser technique. Some examples oλ desiμninμ and λabricatinμ oλ holoμraphic optical elements such as the super-narrowband ilters λor solid-state lasers and laser diodes, laser beam combiners, and collimator siμhts are demonstrated in this chapter. It is shown that the PTR μlass doped with rare earth ions can be used λor desiμninμ lasers with "raμμ relectors and distributed λeedback.
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.
