Embodiment 1
[0025] Such as figure 1 As shown, the present invention is based on a wide temperature laser embodiment 1 of a hexagonal slab structure, including a first Paul prism 1, a 0.57 wave plate 2, a polarizing beam splitter 3, a 1 / 4 wave plate 4, a laser gain medium 5, A high-power laser diode light source 6 and a second Paul prism 7. The high-power laser diode light source 6 is composed of several conduction-cooled laser diodes, arranged around the laser medium for providing pump light; the first Paul prism 1, 0.57 wave plate 2, polarization beam splitter 3, 1 / 4 wave plate 4, laser gain medium 5 and second Paul prism 7 are arranged in sequence to form a polarization coupling output resonant cavity, the output rate of the resonant cavity can be changed by rotating the 1 / 4 wave plate, the first Paul prism 1 and The second Paul prism 7 is placed orthogonally; the laser gain medium 5 is the Nd:YAG medium of the hexagonal slab structure, and the included angles between the optical axis ...
Embodiment 2
[0031] Such as Figure 4 As shown, it can be seen from the figure that the present invention is based on the wide temperature laser embodiment 2 of the hexagonal slab structure, including the first Paul prism 1, the 0.57 wave plate 2, the polarizing beam splitter 3, the 1 / 4 wave plate 4, the laser Gain medium 5, high-power laser diode light source 6, second Paul prism 7 and Pockels cell 8. The first Paul prism 1, the 0.57 wave plate 2, the Pockels cell 8, the polarization beam splitter 3, the 1 / 4 wave plate 4, the laser gain medium 5 and the second Paul prism 7 are arranged in sequence to form a polarization coupling output The resonant cavity can change the output rate of the resonant cavity by rotating the 1 / 4 wave plate, and the first Paul prism 1 and the second Paul prism 7 are orthogonally placed; the laser gain medium 5 is the Nd of the hexagonal slab structure: YAG medium, the angle between the optical axis and the incident surface and the outgoing surface of the slab ...
