Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] Depend on figure 1 , figure 2 and image 3 As shown, a high-power laser resonator includes a total reflection mirror, an output mirror and a laser working medium. The total reflection mirror 1 is composed of the inner surface 4 of the first right-angled circular truncated cone and the outer surface 5 of the opposite right-angled cone. The first right-angled The rotational symmetry axes of the circular truncated cone and the right-angled cone are coaxial, and the inner surface 4 of the first right-angled circular truncated cone and the outer surface 5 of the right-angled cone are all highly reflective surfaces, and the dimensional relationship between them is Φb=3Φa, f=2e, where Φa is The outer surface 5 of the right-angled cone is the diameter of the circle connecting the inner surface 4 of the first right-angled truncated cone, Φb is the diameter o...
