With the rapid development of science and technology, high-power laser systems are increasingly widely used in industrial, medical, and scientific research fields. In the bar packaging, integrating side pump modules not only improves the performance of the laser, but also provides the possibility for miniaturization and integration of the system. Side pumping technology, as an efficient pumping method, is highly valued for its ability to provide uniform pumping light. DuGen Core has achieved significant results in achieving pumped electro-optical efficiency, breaking through the bottleneck of 40% optical to optical conversion efficiency and achieving a maximum optical to optical conversion efficiency of 50%.
The principle and advantages of side pumping technology
Side pumping technology introduces pump light on the side of the laser medium to achieve uniform excitation of the laser medium. Compared with traditional end pumping, side pumping can reduce thermal effects and improve the efficiency and stability of lasers. In addition, side pumping also has the characteristics of compact structure and easy integration, which can achieve more efficient energy conversion and better thermal management. Modular design makes system integration more flexible and can be customized according to different application requirements.
