With the continuous and in-depth application of RealLight‘s billion level 1064nm laser technology in cloud altimeters, our products will gradually extend from the application of a single imaging module in cloud altimeters to the application of imaging systems in cloud altimeters and the networked application of imaging systems in cloud altimeters, realizing the transformation from the application of a single imaging module to a higher level of application, thus exerting a greater driving force on the application of cloud altimeters in imaging.

Technical principles and core advantages

By utilizing the Q-switching technique for the typical wavelength of a 1064nm solid-state laser, it can generate nanosecond level pulses. After its vertical emission, the scattering effect of atmospheric particles such as cloud droplets and aerosols can be utilized to receive it through avalanche photodiodes, which can then convert it into corresponding scattered signals. Based on its excellent penetrability, detailed observations can be made on various parameters of cloud layers within a range of 5-15 kilometers, with a spatial resolution of 5-30 meters.

Compared with 905nm semiconductor lasers, it can achieve higher pulse energy (such as the RealLight AQE series reaching 180mJ), and its wavelength stability is also better. It has great advantages in suppressing the impact of temperature drift (about 0.1nm/℃) of semiconductor lasers on measurement accuracy.

Product application characteristics

RealLight‘s RealShock series solid-state lasers have deeply explored semiconductors and cleverly used the pump active Q-switching technology of semiconductors. They tightly integrate the laser head and power supply into one, perfectly supporting single wavelength output of 1064nm or 532nm, and can be connected to high-end instruments and equipment such as cloud high-altitude instrument systems. The portability of its streamlined OEM control circuit makes it easy to integrate with handheld measuring devices, thus better meeting the needs of mobile measurement in the field.

By adopting the output method of parallel beams with divergence angles less than 0.5mrad, which is adaptable to extreme environments and compatible with the Cassegrain telescope, the signal-to-noise ratio can be greatly improved even in low visibility environments.

Application of 1064nm Laser Cloud Altimeter in the Field by RealLight

Industry application progress

With its ability to synchronously obtain data on cloud base height, cloud layer thickness, and vertical distribution of aerosols, the 1064nm laser altimeter has been widely used in various fields such as meteorological observation and aviation safety. With the further integration of the new generation of equipment launched in 2025 and the integration algorithm of time, the spectrum of the coefficient profile of backward scattering can be directly generated, providing a reliable basis for quantitative analysis of cloud cover.

With the optimization of the self-developed stacked pump source technology for GS series semiconductors, RealLight‘s laser not only has a more compact size, but also greatly reduces its corresponding power consumption (such as pulse width less than 10ns at a repetition rate of up to 10Hz), making it more compatible in some high-end extended applications such as LIBS (laser-induced breakdown spectroscopy).

Technical comparison and market positioning

But with the widespread application of 1064nm solid-state lasers in medical beauty (such as pigment treatment), scientific research and other cross disciplinary fields, the synergistic effect of its technology will promote RealLight to further develop a high-end differentiated competitive path in the high-end cloud high-altitude instrument market, thereby greatly improving the accuracy of aerosol monitoring.
