Embodiment Construction
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0018] see figure 1 Describe this embodiment, a 1Mhz self-Q-switching pulsed laser oscillator, which includes a pumping light source and a resonant cavity. A gain medium 5 is arranged between the mirror 4 and the planar output mirror 6 . The gain medium 5 is a Nd:LuAG crystal, and the doping concentration of neodymium ions in the gain medium is 0.6at%. The pump light source includes a laser 1, a pump light collimating mirror 2 and a pump light focusing mirror 3, and the laser 1 outputs pump light , the pump light enters the resonator after passing through the pump light collimating mirror 2 and the pump light focusing mirror 3 in turn, the laser 1 is a semiconductor laser, the numerical aperture of the semiconductor laser is 0.22, and the output center wavelength of the pigtail...
