Laser cross light source: What is the function of laser point light source?

A laser point light source that uses exciting particles to emit an electro-optic source under the action of excitation. This is a related light source. Since its creation in the United States in 1960, there have been hundreds of laser point sources, and the output wavelengths range from short-wave ultraviolet to far-infrared. So laser cross light source: what is the function of laser point light source?

Laser cross light source: What is the function of laser point light source?

1. Laser spot light sources can be divided into four categories: solid laser sources (crystals and pyrroles), gas laser sources (including atoms, ions, molecules and species), liquid laser sources (including organic events) called active substances) dyes, inorganic liquids and chelates

2. Good color. The color of the laser is very pure, and the single color is more than 10 times higher than the ordinary light source. Therefore, the laser light source is an excellent relevant light source and can be widely used for optical communication.

3. Strong direction. The difference of the laser beam is very small, the level of the measuring mill, the divergence angle of ordinary light or microwave oven is 2 to 3 levels.

4. High brightness. The radiance of the laser focus is 10 to 100 times higher than that of ordinary light.

4. The main advantages of laser point light source are high brightness, good color, low energy consumption, long life and small amount. At the same time, the laser is the only light source with five main advantages. The LED light source is also very powerful, but it is difficult to break through in terms of brightness, so in the future it 5. will be the same level as the laser light source. Of course, these advantages have not yet been fully demonstrated, and the cost of laser light sources is also high. Especially when implementing color display, the industry is currently plagued by the brightness and longevity of green light sources and the unattractive red and blue colors of green light sources.

Laser cross light source: What is the application of laser light source?

Laser point light sources are widely used in various fields of industrial and agricultural production and science and technology, such as laser processing (cutting, welding, drilling, heat treatment, marking), nuclear fusion, isotope separation, medical instruments (scalpel, electric grade, electric carrying)), electrical, and electrical (electric electromagnetic). Detector, optical fiber communication light source, holographic light source, stage art light source, laser video, laser fax, laser typesetting and printing, optical computer, laser weapon, etc.

Laser cross light source: what is the harm of laser light source?

1. A common hazard of laser lights is thermal effects. After accumulating the light source, a large amount of heat energy is generated, thereby increasing the temperature of the beam, the surface of the human body will destroy skin proteins and damage epidermal cells.

2. Shock wave effect formed by laser beam. For example, when the retina on the eye is shocked by high-density photons, when the laser light is fired through the laser light, it will spread to the surrounding area.

In addition to the shock wave effect, there is also an electromagnetic effect and ionization, which causes atoms and molecules in the eye tissue to vibrate and be damaged.
