Red Semiconductor Lasers Are Used in Laser Display
Laser display can truly reproduce the rich and gorgeous colors of the objective world, its color gamut coverage reaches 90%, color saturation is more than 100 times that of traditional display equipment.
Various Laser Technologies' Principle and Application
Laser is especially suitable for material processing because of its characteristics of monochromatic, coherence and parallelism. In addition, its good space control and time control, processing object material...
What Is a Blue Laser Diode?
A blue laser diode is a semiconductor laser that produces a concentrated photon beam with a wavelength of about 400 to 500 nanometers-the visible electromagnetic spectrum that the human eye perceives is blue or violet.
Fiber Lasers: Advantages and Disadvantages
Fiber lasers refer to the use of rare earth doped glass fiber as the gain medium laser fiber laser can be developed on the basis of fiber amplifier; Under the action of pumping light, the high power density is easily formed in the fiber, resulting in the "particle number inversion" of the laser energy level of the laser working material.
How Much Do You Know About Lasers
"Laser" stands for "Light Amplification by Stimulated Emission of Radiation". Laser emits light coherently which allows a narrow spectrum laser beam and a focused light spot on a targeted surface.
Blue Laser over Infrared Laser in Metalworking
However, for the processing of non-ferrous metals, especially copper, due to its low absorption rate of laser in the wavelength range of infrared light, the welding process is often unstable, and welding errors in production often lead to waste, so infrared light is not suitable for the welding of non-ferrous metals.
Laser Pointers' Applications and Hazards
Laser pointers are usually used as an eye-catching point in education, business presentation, and visual demonstrations.
The Cross Line Laser
Cross line laser, and its structure consists of laser source, walk away, expanded beam collimation system and cylindrical lens, a single laser beam into the laser light off the piece...
Dry Fire Training and Laser Bullets
Shooting is a skill that makes perfect. One study found that regular shooters lose up to 20 percent of their skills after a week without training. The only way to prevent deterioration in shooting skills is through repeated practice, but expensive ammunition is a problem for shooters, and dry fire training is a great solution.
The Application of Red Laser in Medical Equipment
The utility model relates to the field of light quantum medical devices, in particular to a light quantum medical device adopting an incoherent monochromatic light source.
How to Choose Between Red and Green Laser Measurement?
The laser used for measurement is much more accurate than a standard tape measure, and allows you to simply place and measure, rather than actually measuring the distance between points.
Near-Infrared and Green Lasers Are Applied to the Stem Cells
Currently, stem cell therapy requires a large number of specific types of human cells. Recently, scientists have discovered through research that irradiating a near-infrared laser to adult stem cells derived from human fat can increase the replication speed of stem cells by 54%...
Blue Light Can Effectively Weaken the Superbug MRSA
Antibiotics is a major medical study in the 20th century. It is well known that excessive use of antibiotics can cause bacteria to develop resistance to drugs, which may make us repeatedly infected and life-threatening again.
Why Choose Infrared Semiconductor Laser for Laser Soldering
In recent years, market demand has promoted the development of technology. Nowadays, when electronic products are becoming more and more refined, traditional soldering iron welding and wave soldering can no longer meet the welding of all electronic products.
The Light-Emitting Principle of Semiconductor Lasers
Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. It has the characteristics of small size and long lifespan...
