摘要:
The present invention relates to an optically pumped solid state laser device, comprising one or several solid state laser media (100) in a laser resonator and one or several pump laser diodes (200) and pump radiation reflecting mirrors (300). The laser resonator is formed of one or several first resonator mirrors arranged at a first side of the solid state laser media(100) and one or several second resonator mirrors (310, 320, 330) arranged at a second side of the solid state laser media (100). The first and second resonator mirrors are arranged to guide laser radiation (500) on at least two different straight paths through each of said laser media (100). The pump laser diodes (200) are arranged to optically pump the solid state laser media (100) by reflection of pump radiation (510) at said pump radiation reflecting mirrors (300). The pump radiation reflecting mirrors (300) and the second resonator mirrors (310, 320, 330) are integrally formed in a single mirror element (600). With this design of the solid state laser device an easy alignment of the pump optics and an enhanced gain of the laser device are achieved. The proposed solid state laser device can be realized in a compact form.
