Abstract

resumo dispositivo laser em estado sólido bombeado opticamente a presente invenção refere-se a um dispositivo laser em estado sólido bombeado opticamente, que compreende um meio laser em estado sólido (300-302) em um ressonador laser. diversos diodos de bombeamento laser (100) são dispostos para bombear opticamente o mencionado meio laser em estado sólido (300-302) por meio de reflexão da radiação de bombeamento em um elemento espelhado (200) disposto sobre o eixo óptico do ressonador laser. o elemento espelhado (200) é projetado para direcionar a mencionada radiação de bombeamento para o meio laser em estado sólido (300-302) e formar ao mesmo tempo um dos espelhos de ressonador do ressonador laser. com este projeto do dispositivo laser em estado sólido, atinge-se fácil alinhamento da óptica de bombeamento. o dispositivo laser em estado sólido proposto pode ser realizado de forma compacta.
