Abstract

FIELD: quantum electronics. SUBSTANCE: device has excitation system, active element which is made from crystal containing neodymium, resonator which is shaped by output semitransparent mirror and by end mirror which reflects al light for generated wavelength. Novel feature of device is production of active element from neodymium-containing crystal in which rate of section of forced transition to wavelength which is safe for eyes to section of forced transition to competing wavelength of 1.06 mcm is not less than 0.085 and not greater than 1. In addition crystal of active element contains chrome ions Crand/or Cr. Active element may be made from crystal of gadolinium-gallium garnet. EFFECT: simplified design, increased efficiency, increased power at wavelength of 1,4 mcm which is safe for eyes. 1 dwg, 3 cl

Цель изобретения - упрощение конструкции лазера, повышение КПД и энергии излучения лазера на безопасной для глаз длине волны 1,4 мкм. Безопасный для глаз твердотельный лазер содержит оптически связанные систему накачки, активный элемент из содержащего неодим кристалла, резонатор, образованный выходным полупрозрачным зеркалом и концевым зеркалом с полным отражением на длине волны генерации. Новым в лазере является выполнение активного элемента из содержащего неодим кристалла, в котором отношение сечения вынужденного перехода на безопасной для глаз длине волны к сечению вынужденного перехода на конкурирующей длине волны 1,06 не меньше 0,085 и не больше 1, выполнение активного элемента из кристалла, дополнительно содержащего хром в виде ионов Сг4+ и/или Сг3+, выполнение активного элемента из кристалла гадолиний-галлиевого граната.The purpose of the invention is to simplify the design of the laser, increasing the efficiency and energy of laser radiation at an eye-safe wavelength of 1.4 microns. An eye-safe solid-state laser contains an optically coupled pump system, an active element made of a neodymium-containing crystal, a resonator formed by an output translucent mirror and an end mirror with full reflection at the generation wavelength. New in the laser is the implementation of the active element from a neodymium-containing crystal, in which the ratio of the cross section of the forced transition at an eye-safe wavelength to the cross section of the forced transition at a competing wavelength of 1.06 is not less than 0.085 and not more than 1, the execution of the active element from the crystal is additionally containing chromium in the form of Cr 4+ and / or Cr 3+ ions, the implementation of the active element from a gadolinium-gallium garnet crystal.
