Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] Figure 4 It is a schematic structural diagram of an active illumination beacon system based on an alkali metal vapor laser according to the present invention.
[0029] An active illumination beacon system based on an alkali metal vapor laser according to the present invention includes a high-power single-frequency alkali metal vapor laser 1, an illumination light emitting and beacon light receiving device 2, a beacon light amplification device 3, and an amplifying beacon light Receiver 4.
[0030] In the embodiment, the alkali metal vapor laser is a rubidium vapor laser (wavelength 795nm), and the alkali metal vapor nonlinear effect used is the stimulated Raman effect in rubidium vapor, and the specific working process is as follows:
[0031] S1 outputs 795nm illumination light through high-power single-frequency rubidium vapor laser ...
