the manufacture base of green laser pointer is still in the process

There are also two more special laser. One is the carbon dioxide laser, can be called "stealth" because it sends a laser wavelength of 10.6 microns, "body" at the infrared region, the naked eye can not perceive that it works with continuous, pulsed two. Connection produced by the laser power up to 20 kilowatts or more. Pulse generated by the laser wavelength of 10.6 microns is the most powerful kind of laser. People have been using it to "fight" out of the neutron in the nucleus. The emergence of carbon dioxide lasers is significant progress in the development of laser, light weapons and nuclear fusion research is the significant results. The manager is inspecting the construction site of manufacturing base of 200mW green Laser Pointer.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 50mW green laser pointer 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. 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. Mentioned earlier ruby laser is a solid-state lasers. Early ruby laser is used as the excitation source common source. Now the production of ruby laser has developed many new products, categories also increased. In addition, incentives, also divided into several, in addition to optical excitation, there are discharge excitation, thermal excitation, and chemical and other incentives. The construction of the manufacture base of  green laser pointer is still in the process.

Also commonly used in solid-state 100mW green laser pointer  yttrium aluminum garnet laser, it's working material is alumina and yttria synthetic crystals, and mixed with neodymium oxide. Laser is the neodymium ions in the crystal release, the human eye can not see infrared light, can work, can also be pulsed manner. Because of this the laser output power is relatively large, not only militarily useful, and can be widely used in industry. In addition, yttrium aluminum garnet laser in the laser or liquid dye laser, cataract and glaucoma treatment is very effective.
