Customized High-power Laser Pointer With Original Surface
In 2017, the 1.2-meter telescope optical system of the Yunnan Observatory of the Chinese Academy of Sciences was upgraded. Improved laser pointer optical system efficiency. Lay a good foundation for lunar laser ranging. Also. The research team has also done a lot of work in weak signal detection and data processing. The average distance between the earth and the moon is 384403.9 kilometers. In the ranging experiment, the researchers used a common optical path to measure distances through a 1.2-meter telescope laser ranging system. The laser has a wavelength of 532 nanometers and a pulse width of 10 nanoseconds. The frequency is 10 Hz. During the test, the single pulse energy was 3.3 joules.

On the evening of January 22 from 21:25 to 22:31. The measured data segment shows that the distance from the Apollo 15 laser pointer reflector to the station is 385823.433 km to 387119.600 km. Ranging accuracy is better than 1 meter. At present, the only countries in the world that have successfully achieved lunar laser ranging are the United States, France, and Italy. This time, the Yunnan Observatory successfully implemented lunar laser ranging, filling a gap in the field of lunar laser ranging, and will provide ranging technical support for the implementation of the Tianqin project. Therefore, a laser processing head tailored to the needs of the application can optimize process efficiency and minimize equipment cost and size by focusing the light where it is needed. The company's original diamond turning capabilities can be achieved. Custom high-power laser pointer optical system with original surface. Used for custom beamforming in advanced laser processing.
