The table will introduce the difference between the blue ray laser pointer pen and green ray laser pointer pen

Some lasers can produce different frequencies of the laser, but these lasers are isolated from each other, use is separate. Second, the laser is coherent light. Coherent light is characterized by all of its light waves are synchronized, the entire beam of light like a "wave train." Again, the laser is highly concentrated, meaning that it would go a long distance to appear scattered or convergence phenomenon. Laser classification categories to see from what angle, red laser, blue laser, green laser, based on the frequency distinction, from the principle of points, there is helium - neon laser, carbon dioxide laser, diode laser, excimer laser, dye laser, argon ion laser, nitrogen laser, YAG laser, so there are many. The table will introduce the difference between the blue ray     100mW green laser pointer and green ray   laser pointer pen    .
To be divided from the continuity of continuous laser and pulsed laser, pulsed laser with microsecond (10e-6 seconds), also nanosecond (10e-9 seconds), picosecond (10e-12 seconds), and femtosecond (10e- 15 seconds) laser. In addition the intensity of the laser generally be divided into, first, second .... and so on, the higher the level the greater the intensity corresponding to the requirements more stringent protective measures by band laser points, can be divided into visible light, infrared, ultraviolet, X-ray, multi-wavelength tunable, infrared and ultraviolet current industrial laser. Such as CO2 laser 10.64um infrared laser, krypton lamp-pumped YAG laser 1.064um infrared laser, xenon lamp-pumped YAG laser 1.064um infrared laser, the semiconductor side-pumped YAG laser 1.064um infrared laser. Red ray   laser pointer pen     is easier to be produced.
Many different types of lasers can be divided into solids, gases, liquids, such as semiconductors and several types of dye: generally small and rugged solid-state lasers, high power pulsed radiation, a wider range of applications. Such as: Nd: YAG laser. Nd (neodymium) is a rare earth element, YAG yttrium aluminum garnet behalf, and the ruby crystal structure is similar. Semiconductor lasers small size, light weight, long life, simple structure, particularly suitable for aircraft, ships, vehicles and spacecraft use. Semiconductor lasers can be applied electric field, magnetic field, temperature, pressure, etc. to change the laser wavelength, the laser can be directly converted to electrical energy, so rapidly. Red ray  green laser pointer has the full-blown technology.
Gas laser with gas as the working material, monochromatic and coherent nature of good, up to thousands of laser wavelength, are widely used. Gas laser structure is simple, low cost, easy to operate. In the industrial and agricultural, medical, precision measurement, holography techniques are widely used. Gas lasers with electrical energy, thermal energy, chemical energy, solar energy, nuclear energy and other incentives. Work with liquid dye laser dye material came in 1966, is widely used in various scientific fields. Has now been found to produce the dye laser, about 500 or so. These dyes can be dissolved in alcohol, benzene, acetone, water or other solutions. They also can be included in the organic plastic in order to appear solid, or sublimation of steam, gaseous form. The wavelength of red ray   200mW green Laser Pointer is approximately 600nm or more.
So dye laser is also known as "liquid laser." Dye laser is characterized by the wavelength continuously adjustable. Wide range of laser fuel, low cost, high efficiency, output power and solid-state lasers with comparable gas, used in spectroscopy, photochemistry, health and agriculture. Infrared lasers have many types, wide range of applications, it is a new type of infrared radiation, the radiation is characterized by high strength, good color, good coherence, direction and strong. X-ray lasers in scientific research and the military has an important value, used in laser anti-missile weapons, has an advantage; biologist with the X-ray laser to study the molecular structure of living tissue or detailed understanding of cell function. The red ray    50mW blue violet laser pointer adopts the mature semiconductor-made process materials.
