Embodiment 1
[0024] Depend on figure 1 It can be seen that the adjustable F-P integral cavity device of this embodiment is connected by a light source 1, an optical isolator 2, a first plane mirror 3, a matching lens 4, an F-P integral cavity mirror group 5, a high-voltage amplifier 6, a signal source 7, and a second plane mirror 8 constitute.
[0025] The laser of this embodiment is used as a light source 1, and emits laser light with a wavelength of 633nm. An optical isolator 2 is installed at a position 10mm away from the laser on the outgoing optical path of the laser light. The center wavelength of the optical isolator 2 is 650nm, and the applicable wavelength range is 630 to 700nm. , the transmittance is 75%, and the isolation is 30dB. A reflective plane mirror group is installed at a position 220 mm away from the optical isolator on the exit light path of the optical isolator 2 to adjust the optical center of the laser light path. The reflective plane mirror group includes the first...
