Combining the advanced technology of micro laser with the requirements of meteorological radar not only better meets our in-depth research on weather, but also provides us with new possibilities for future weather forecasting.

With the continuous development of microchip lasers, their compact structure, high stability, low power consumption and other excellent working characteristics are playing an important technical role in the transformation and development of new generation meteorological radars. By adopting its unique imaging technology, this type of laser has opened up a new path for atmospheric detection technology, especially for the development of radar systems with meter scattering (especially micro pulse radar).

Based on the core advantage of its highly distinctive microchip laser, which is its miniaturized design, its typical size is only a few centimeters, which can be directly integrated into the radar system, providing great guarantee for the reliability and maintainability of the radar and greatly reducing its cost. Through its working wavelength of 532nm or 1064nm, it is particularly capable of generating strong Mie scattering effects with small particles of various aerosols in the atmosphere, thereby greatly improving its detection sensitivity. Compared to traditional LiDAR, the system using microchip laser not only reduces the volume by more than 60%, but more importantly, reduces power consumption by 40%, which is of great significance for the deployment of mobile platforms such as airborne and shipborne. With the in-depth research and development of the 2024 Antarctic scientific expedition mission, such as the successful implementation of polarized micro pulse radar equipped with micro plate lasers for continuous observation of aerosols within a range of 15km, a series of scientific exploration achievements have fully demonstrated the enormous application prospects and profound scientific significance of this technology.

With in-depth research on cloud physics, the radar technology of microchip lasers can accurately identify the vertical hierarchical structure of clouds. By comprehensively analyzing a series of parameters such as cloud base height and cloud top temperature, a good prediction of the development trend of severe convective weather can be made. Based on the in-depth application of the microwave laser composite radar system deployed in November 2024 in Wenquan County, Xinjiang, the laser technology of micro chips has been ingeniously integrated with synchronous observation of clouds and aerosols, and its spatial resolution has been pushed to the level of 50 meters.

As the technology of micro chip lasers continues to advance, although there is still a relatively low peak power gap, its detection range is gradually expanding to a range of 20km through the integration of multiple module arrays.

The adjustability of multiple parameters of the Beijing RealLight  MCA-R laser not only meets the current technical requirements of meteorological radar, but also provides a reliable technical foundation for the development of meteorological radar with higher technical indicators in the future. The pump technology of semiconductors continues to mature, and in the future, the laser radar of microchips will not only be able to locate typhoons more accurately, but also play a greater role in monitoring extreme weather conditions such as sandstorms.

Based on the widespread popularity of such devices, not only can the deployment cost of China’s meteorological radar network be greatly reduced, but it will also promote a big step forward in the construction of China’s three-dimensional observation system.
