In the field of modern science and technology, semiconductor lasers have become a shining star in the field of optical technology with their unique performance and broad application prospects. Among them, the 460nm 60W semiconductor laser has become the pinnacle of the blue light source field with its high power, high efficiency, high purity and other characteristics. As can be seen from the video, for a 60W laser, we need to add a heat sink to the bottom of the power supply, which is an aluminum heat dissipation module with 3 fans. On the back of the laser power supply, there are 3 working modes to choose from: CW/TTL/Analog. The two white ports on the data cable are the ports for the fan power supply, which also need to be plugged in. There are multiple groups of laser chips inside the laser. Here, two synchronous data lines are used to control the laser. The customer needs to be able to minimize the laser spot at a specified working distance. A beam expander collimator is added here...

Development history of  405nm blue-violet laser semiconductor laser The 405nm laser has advantages in many areas. This band is representative of the shortest wavelength range of visible light and is also the working band of HD HD DVD. The origin of the blue-violet laser 1. In the mid-1990s, blue-violet lasers appeared The development of blue-violet lasers originated from the development of a 400-410 nm gallium nitride crystal blue-violet laser semiconductor laser from Nichia Corporation in Japan in 1996 to further increase the storage capacity of DVD discs. Because of its shorter wavelength. The focus spot is smaller, the same size DVD disc is 40 times larger than the ordinary CD disc, 6-7 times the ordinary home DVD disc, but the laser power applied to the DVD is very small. With the continuous expansion of laser power, the blue-violet laser with a service life of more than 3,000 hours in 1999 was introduced. 2. Several major Japanese companies compete to produce blue-v...

Principle and experimental design of a small 473nm laser 473nm solid laser is different from a 45nm semiconductor laser; The  473nm laser  is a high-efficiency intracavity frequency-doubled blue laser with a YAG crystal, LBO crystal, and a stable 473nm blue light output. 473nm laser experimental device: We used a 808nm LD as the pump source, and provided a focusing lens to focus on the laser crystal yttrium aluminum garnet (Nd3+:YAG). Forming a laser cavity by a flat concave mirror (output mirror), Thereby producing a 946 nm pulse wave output, The LBO crystal was used for frequency doubling in the cavity to obtain 473 nm blue light. The schematic diagram is shown below. The LD uses Nlight’s 1.5W 808nm semiconductor laser. The optical path should use a short focal length focusing lens with a diameter of Φ5mm and a focal length of F=3.5mm. In order to obtain a higher output power and a better beam quality, the lens optical surface film system for collimation i...
