Abstract: PROBLEM TO BE SOLVED: To provide a system where power as energy required for controlling a laser optical system is generated within the optical system, without having to depend on an external supply by making effective use of laser energy leaking from the laser optical system, which conventionally has merely been a loss. SOLUTION: In the power generation system using energy leaking from the laser optical system, a translucent-type reflector is deliberately used, and solar cells are placed behind the reflector. Thus, the energy of laser light, passing through, is used to generate power. The amount of electricity generated is adjusted, by varying the permeability of the reflector to vary the amount of energy which reaches the solar cells. At this time, a photoelectric element, corresponding to the wavelength of the laser is selected and used. Thus, energy can be extracted at high conversion efficiency. Further, thermoelectric elements are caused to generate electricity, utilizing heat emitted from the laser optical system.
