The 520nm 40W fiber-coupled laser belongs to the visible light band, which makes it perform well in applications that require a specific color light source. At the same time, its power output of up to 40 watts ensures powerful laser energy and is suitable for a variety of high-demand processing and measurement tasks. The bottom of the laser head has a heat sink, which is an aluminum heat dissipation module with 3 fans. There are 3 working modes to choose from on the back of the power supply: CW/TTL/Analog. The regulator button on the power supply is used to adjust the operating current, thereby adjusting the laser output power. Fiber-coupled lasers efficiently couple the laser beam generated by the laser diode into the optical fiber through precise fiber coupling technology. This process requires precise focal length adjustment and angle control to ensure that the beam can enter the optical fiber without loss and be stably transmitted along the path of the optical fiber. Fiber coupling...

Indium gallium nitride (InGaN) laser diodes can directly produce laser diodes that emit blue light, but it is difficult to produce laser diodes that emit green light directly, especially those that are considered to be truly green: early green laser diodes Usually has a slight cyan projection. As a commercial pioneer of green InGaN laser diodes, OSRAM Opto Semiconductors has been promoting the development of long-wavelength laser diodes. A laser based on InGaN-based direct-emitting green light has been introduced, with wavelengths from 510 to 530 nm, which can be used for micro-projection. And other red, green, blue (RGB) or green laser applications. (Osram also produces blue laser diodes.) The new lasers are available in TO38 ICut or TO56 packages (with a flange diameter of only 3.8 mm) with integrated photodiodes, typically with a parallel divergence angle of 7°and a vertical divergence angle of 22°, small enough to pass The relatively simple optics are cyclized and collimate...
