Embodiment Construction
[0019] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings, so as to better understand the present invention.
[0020] like figure 1 As shown, a compact and stable high peak power fiber output laser, including a resonant cavity, a half-wave plate (7), a polarization beam splitter (8) and a photodetector (9), are arranged in sequence along the optical path direction, and it is characterized in that, The resonant cavity includes a Paul prism (1), a passive Q-switching crystal (3), a laser crystal (4) and an output mirror (6) arranged in sequence; A coupling lens (10), an optical fiber (11) and a collimator lens group (12) are provided in sequence.
[0021] like figure 2 As shown, the Paul prism 1 includes two inclined planes a and b perpendicular to each other, a and b intersect on the line l, the midpoint of l is M, the Paul prism 1 also includes a longitudinal plane c, and the longitudinal plane c is a ...
