Problems solved by technology
If the laser active lighting system is to be applied on the lunar surface, it must overcome the impact of the harsh lunar surface environment, especially the high and low temperature environment on the lunar surface, which will affect the optical system, output power and service life of the laser active lighting system. It may even cause some devices to fail, making them unable to use normally

The invention discloses a novel laser active lighting system, which includes a laser module, a temperature control module, a power supply module, an optical fiber module, an optical shaping module and an incubator; the laser module, the temperature control module and the power supply module are placed inside the incubator, and the optical fiber module And the optical shaping module is placed outside the incubator; the incubator box is made of polyimide material, the optical fiber module is made of polyimide optical fiber, and the optical shaping module is made of plano-convex optical lens made of fused silica optical material. Through the solution of the invention, the laser active lighting system can withstand high and low temperatures of -190°C to +130°C, and can be used normally on the surface of the moon.
Description
technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to a laser active lighting system. Background technique [0002] Laser technology has broad application prospects in the field of lunar exploration. Apollo 15 and 17 measured the surface temperature of the moon at their landing sites, and the measured results were -181°C to +101°C and -171°C to +111°C respectively. If the laser active lighting system is to be applied on the lunar surface, it must overcome the impact of the harsh lunar surface environment, especially the high and low temperature environment on the lunar surface, which will affect the optical system, output power and service life of the laser active lighting system. Even cause some devices to malfunction, making it unable to use normally. Therefore, the laser active lighting system used on the lunar surface must have the ability to withstand the above-mentioned high and low temperatures. Contents of the...
