Advantages of  355nm UV laser  marking machine Ultraviolet laser marking machine has the characteristics of short wavelength and small spot. It adopts 355nm laser, which is the first choice for high precision laser engraving machine and marking machine. Ultraviolet laser marking machines are known as “photo-etching” effects. High-energy ultraviolet photons directly destroy the chemical bonds of materials by “cold treatment”, and the processed parts have smooth edges and minimal carbonization. In addition, UV laser energy can be effectively absorbed by most materials and has good focusing performance, so it can be finely micromachined in a small space area, which has very high research value and broad application prospects. In layman’s terms, all lasers are excited by their working medium and excited to an excited state. Some photons (atoms) are on a low-energy step called metastable state. The higher the absorption energy, the higher the energy level step, and the constant trans

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-viole

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 is require

Analysis on Demand Growth of Ultraviolet Laser Industry The output wavelength of the ultraviolet laser is below 0.4 μm, which is characterized by short wavelength, concentrated energy, and high resolution. Infrared or visible light is usually processed by means of concentrated localized heating to melt or vaporize the material. However, this heating can cause severe damage to the surrounding area, thus limiting edge strength and the ability to produce small, fine features. Ultraviolet lasers are chemical bonds that directly destroy the atomic components of the connecting substance. This process of separating matter into atoms is a “cold” process that does not produce heating to the periphery. On the other hand, most materials can effectively absorb ultraviolet light, which can be used to process materials that cannot be processed by infrared and visible lasers. Therefore,  ultraviolet lasers  have a great advantage in processing metal materials (especially surface treatment proces

How is the white laser produced? White laser principle We all know that lasers have monochromatic properties. A laser corresponds to a wavelength that produces a color. The picture below is the color distribution of lasers of different wavelengths. The white laser is not directly generated by the laser machine. It is synthesized by red/green/blue laser. e.g. Below  CivilLaser ‘s white laser, There are 3 kinds of lasers inside, and then they are concentrated by the lens system to the same light exit, forming a white laser. White laser RGB Laser system (Red / Green / blue can be used alone) White laser / RGB laser module

The difference between single mode laser and multimode laser The beam quality of a  single-mode laser  is good, and the spot is round. But many wavelengths of laser can not do TEM00. Especially high-power lasers, multiple LD-synthesized lasers, they are multimode lasers. Got to  CivilLaser .com find more single mode laser and multimode laser.

Laser positioner — How to choose the laser output power? Dot laser, line laser, crosshair laser , etc. Laser modules are widely used as positioners in industrial production. Many customers don’t know how to choose the power of the laser. The power is too small for the operator to see the laser; The power is too high, the laser is too dazzling, affecting normal work. So how do you choose the laser power at different distances? CivilLaser  take the red light as an example and sort out a table for your reference. Laser module — The relationship between the power,brightness and working disance. OUTPUT POWER BRIGHTNESS LEVEL BEST WORKING DISTANCE DESCRIPTION <5mw Micro Light < 0.5 meter 1.
