Abstract

resumo dispositivo laser de estado sólido bombeado opticamente a presente invenção refere-se a um dispositivo laser de estado sólido opticamente bombeado, compreendendo uma ou várias mídias de laser de estado sólido (100) em um ressonador laser e um ou vários diodos laser de bomba (200) e espelhos refletores de radiação da bomba (300). o ressonador laser é formado de um ou vários primeiros espelhos de ressonância dispostos em um primeiro lado das mídias de laser de estado sólido (100) e um ou vários segundos espelhos de ressonância (310, 320, 330) dispostos em um segundo lado das mídias de laser de estado sólido (100). o primeiro e o segundo espelhos de ressonância são dispostos para guiar a radiação laser (500) em ao menos duas trajetórias retas diferentes através de cada uma das ditas mídias de laser (100). os diodos laser de bomba (200) são dispostos para bombear opticamente as mídias de laser de estado sólido (100) pela reflexão da radiação da bomba (510) nos ditos espelhos refletores de radiação da bomba (300). os espelhos refletores de radiação da bomba (300) e os segundos espelhos de ressonância (310, 320, 330) são integralmente formados em um único elemento de espelho (600). com este design do dispositivo laser de estado sólido, consegue-se um alinhamento fácil dos elementos ópticos da bomba e um ganho aumentado do dispositivo laser. o dispositivo laser de estado sólido proposto pode ser criado em uma forma compacta. 1/1
