Their scalar product is: He-Ne solid-state lasers, semiconductor lasers. Temporal coherence and monochromaticity: temporal coherence and monochromaticity in the simple relationship between the monochromatic higher the longer the coherence time. Best passive optical cavity mode frequency band width in general, single-mode frequency stabilization of gas lasers, monochrome, usually in the 106-103 Hz, solid-state laser monochrome poor, mainly due to the gain curve of the working substance width, it is difficult to work in single mode. Semiconductor laser monochrome worst. Laser intensity (coherent light): the laser output power is very high due to the laser photon degenerate very high degree. Improve the output power and efficiency is an important subject of laser development. This kind of 100mw green laser is highly recommended for the customer.
Such as the application of solid-state lasers, Q-lock, membrane technology, allows the pulse width of 10-12 seconds. A gigawatt-level (109 W) Q-switched laser pulse focused to the spot diameter of 5 microns, the available power density of 1015 watts / cm 2. Classification of lasers. The laser has a different classification methods, generally classified according to the different working medium can be divided into solid-state lasers, gas lasers, liquid lasers and semiconductor lasers. In addition, the laser output mode can be divided into CW lasers and pulsed lasers, the laser pulse peak power can be very large, you can also by the frequency of light and luminous power size classification. The customer needs 100mw green laser to be used in various locations.
Solid-state lasers. Generally speaking, solid-state laser device is small, sturdy, easy to use, the output power characteristics. This laser medium is uniformly mixed with a small amount of active ions in the crystal or glass as a matrix material, ruby and glass, yttrium aluminum garnet (YAG) crystals doped trivalent neodymium ion lasers, It launches the near-infrared laser 1060nm. Continuous power solid-state lasers up to 100W or more, the pulse peak power up to 109w. Gas lasers. Gas laser has a simple structure and low cost; easy to operate; the working medium is uniform, and good beam quality; and long time stable continuous operation characteristics. The high economical efficiency of 100mw green laser can save much money for the customer.
This is also the varieties most widely used class of lasers, occupies up to 60% market. Among them, the helium-neon laser is the most commonly used. Semiconductor lasers. Semiconductor lasers based on semiconductor materials as the working medium. The more mature GaAs lasers, emission 840nm laser. Another aluminum-doped GaAs, chromium sulfide, zinc sulfide, and other lasers. Incentives bright pumps, and electrical stimulation. The laser volume is small, light weight, long life, simple structure and strong, particularly suitable for use in aircraft, vehicles, and spacecraft. Greatly promoted the development of semiconductor lasers in the late 1970s, due to the development of fiber-optic communications and optical disc technology. Use the high quality and performance cheap Laser Pointers in the practical application.
Liquid lasers. Commonly used dye lasers using organic dyes as the working media. In most cases the organic dye dissolved in a solvent (ethanol, acetone, water, etc.), but also work for the vapor state. Use of different dyes available to different wavelengths of the laser (in the visible range). Dye lasers generally use the laser as the pump source, such as commonly used argon ion lasers. It has the advantage of the output wavelength continuously adjustable, wide coverage and therefore are widely used. Laser principle. Stimulated absorption and spontaneous emission. Ordinary common light source of the light-emitting (such as lights, flame, sun light) is due to substances in the external energy (eg solar energy, electricity, heat, etc.) role. Actually, the double-colored 100mw green laser is the favorite of the customer in the current market.
