In gas lasers, the most common is helium-neon laser. The world's first helium-neon laser is the second shortly after the first ruby laser in 1960, Bell Laboratories in the United States by the Iranian physicist Jia Wan made. As the helium-neon laser emits monochromatic beam direction and good, can work, so this laser is the most used lasers today mainly used in the holographic precision measurement, collimator positioning. Gas lasers is another typical argon ion laser. It can send bright blue-green shade, continuous work, the output power of 100 watts. The representative of the customer will perform the manufacture supervision of Laser Pointer this week.
Such lasers in the visible region is the highest output power of a laser. Because of its blue-green laser is emitted, so the most used on the eye, blue-green because the human eye's response is very sensitive to the retinal heme, lutein can absorb green light. Thus, argon ion laser eye surgery, can rapidly form a local heating, the protein into a gel state of the retina, which is the ideal light source for welding the retina. Argon ion laser emits blue-green laser can deep sea floor, without being absorbed by seawater, which can be used underwater survey operations. The new sales strategy of Green Laser Pointer increased the revenue of the company.
Also known as liquid laser dye laser, because the activation of these lasers is that some organic dye material dissolved in ethanol, methanol or water and other liquids in the form of the solution. In order to stimulate them to emit a laser, commonly used for high-speed flash laser source, or by other laser emits very short pulses of light. For liquid laser emits laser spectroscopy, laser chemistry and other scientific research, is of great significance. Chemical laser is a chemical reaction to generate the laser. Fluorine atoms and hydrogen atoms, such as chemical reactions, can generate hydrogen fluoride molecules in the excited state. Thus, when the two gases mix quickly to be able to produce the laser, so no other energy can be obtained directly from the chemical reaction is very strong light. The inspection includes the self-inspection of Green Laser Pointer and the mutual inspection of Green Laser Pointer .
These lasers are more suitable for field work, or for military purposes, it is fear of death ray weapon is a result of application of chemical lasers. In today's lasers, and some are made with the semiconductor. They are small, long life, motivation is simple (usually electrical stimulation), low threshold current, easy-to-scale production, the early output of the laser semiconductor laser coherence, direction and other poor performance, the more types of output laser frequency less, mostly in the infrared region, but now with further research and expansion of semiconductor materials and structures, semiconductor lasers, such as the family appeared edge-emitting lasers, quantum well lasers, vertical cavity surface emitting lasers, and so the output performance of the new laser members, the type of the output laser frequency in the visible region are also widely distributed. The customer needs more discount for the product of Green Laser Pointer.
In particular, vertical cavity surface emitting lasers, in addition to single-longitudinal-mode output, low threshold current start-up and other outstanding features, but also on a large scale in the production process and the array of technology, so that semiconductor lasers can output high power laser and further reduce the production cost of semiconductor lasers, which will help the popularity of laser applications. Currently, the semiconductor laser is the most widely used laser family of one, such as optical communication (such as fiber optic communications), optical storage and read (ie, CD-ROM and CD-ROM), optical switches, optical logic devices, and so on.
