Potassium and ammonium hydrogen phthalates KHC6H4(COO)2and (NH4)HC6H4(COO)2- new organic crystals for Raman laser converters with large frequency shift

Abstract: Raman-induced many-phonons Stokes and antiStokes generation in a orthorhombic crystals KHC6H4(COO)2 and (NH 4 )HC 6 H 4 (COO) 2 under picosecond pumping has been observed. All recorded nonlinear lasing lines in the visible and near-IR regions are identified and attributed to the χ (3) -promoting vibration modes of these orthorhombic phthalates. Room-temperature SRS and RFWM spectrum of an orthorhombic KHC 6H4(COO)2 single crystal

“…Одними из перспективных объектов для данных целей являются кристаллы бифталата рубидия. Соединения семейства бифталатов привлекают внимание в связи с уникальным сочетанием оптических, электрических и механических свойств, благодаря чему они находят разнообразные применения в оптоэлектронике и акустооптике [5,6], в конвертерах лазерного излучения [7], электрооптических модуляторах [8], монохроматорах мягкого рентгеновского излучения [9]. При этом кристаллы бифталаты относятся к сильным пьезоэлектрикам, в частности имеющим рекордные значения чувствительности на прием акустических сигналов [10].…”

“…These crystals also have remarkable piezoelectric properties (Belyaev et al, 1969;Belikova et al, 1974) that make it possible to construct sensitive receivers of acoustic waves, as well as good acousto-optic characteristics (Khan & Narasimhamurty, 1982), pronounced pyroelectric properties (Varma & Raychaudhuri, 1989) and nonlinear optical properties, which are used in Raman converters of laser radiation (Kaminskii et al, 2009) and in up-conversion solid-state dye lasers (Benedict et al, 2003;Enculescu & Neumann, 2011).…”
