高功率激光模块设计：基于三个LD Bar条的漫反射器结构

Three LD Bar strips (Focus Light, USA) are symmetrically distributed at 120° around the surface of a ceramic diffuse reflector with an inner diameter of 5.5 mm and a thickness of 0.5 mm. The distance between the emitting surface of the LD and the axis of the crystal rod is 6 mm. Each LD Bar strip has a maximum output power of approximately 220 W, while the laser module can provide a maximum pumping power of 660 W.
