The specific requirement of green laser pointer

The maintenance of green laser pointer is very easy to carry out. China's commercial fiber lasers now entirely dependent on imports, because we have not implemented the commercialization of optical fiber lasers and industrialization. Development of our fiber laser is not lagging behind, has several units in a row for more than 200W output power, but China's industrialization fiber lasers has lagged far behind. The following analysis of the industrial development of China's optical fiber laser reasons for delay. As mentioned earlier, the development of all-fiber laser requires five key technologies, it is easy to see that five key technologies in addition to diode-pumped lasers, the other four key technologies are all closely related with the fiber-optic technology, precisely, is the energy optical fiber technology are closely related. Optical fiber technology is based on the signal energy-based technology developed, and the signal is mainly for optical fiber communication technology services, therefore, the energy of laser and optical communication technology through the two optical fiber link of this particular medium, so that in the fiber development and production of optical devices and the unit can be deeply involved in both technology and become the core strength. The worker should pay attention to the specific requirement of green laser pointer .
In the optical communication into a valley when the fiber laser to achieve a historic breakthrough coincides with the time, many foreign development of fiber optic devices in optical communication unit of production began to shift energy research and development of optical devices, to seek new opportunities to expand to survive space. Fiber laser energy into the development of these units has become an important force in the development of fiber lasers, fiber lasers for the development of new all made a great contribution. China's production and development of devices for optical fiber unit, although very much, but the overall level of technology is weak, the optical communication into a valley, when the unit is basically only choice in the industry for bankruptcy or shut down production lines in two ways, unable to invested huge resources in energy research and development of optical devices, so when the rapid development of all-fiber laser optical devices made of energy, when the urgent needs of our country in this area is basically a blank. For our first unit in the development of fiber lasers, the face of the domestic situation, the development of all-fiber laser is basically no foundation at all, so the plastic lens focus end-pumped external cavity of the program to become a realistic choice. The manufacture requirement of 200mw laser pointer is very strict.
This structure is very close to the traditional solid-state lasers, fiber-optic technology, dependence on low, non-fiber optic technology to production. However, practice shows that only the use of all-optical fiber laser structure in order to fully reflect the overall consistency, integrity, harmony and matching, the use of fully demonstrated the advantages of fiber lasers, therefore, all-fiber structure of the program more in line with the nature of the development of fiber lasers law, so, in the world, all-fiber laser into the mainstream program has its inevitability. All-fiber lasers and fiber-optic laser technology requires energy technologies combine, to some extent, the optical fiber laser technology in the development of a large proportion, therefore, the energy-energy laser technology and the development of optical fiber laser technology is not or missing legs. At present, engaged in the development and production of optical devices unit is still mainly concentrated in the industrial chain of optical fiber communication among the few involved in energy laser technology, which is facing the development of our fiber lasers huge problems. More discount is available for the large quantity order of green laser pointer .
This article hopes to engaged in the development and production of fiber optic devices unit exceeded industry boundaries, concerns the development of fiber lasers, active participation in the new energy research and development of optical devices, fiber lasers for our domestic and industrial contribution. It should be noted, the new high-power all-fiber laser with a broad market, the development of energy-based optical devices, optical devices developed for the production unit is the most promising. It should also be noted that foreign fiber laser is also achieved rapid development in recent years things, although China's current level of the gap with foreign great, but time is not long behind, as long as the development of China's optical fiber devices related products production units active in research and development work, we are able to develop the production of fiber lasers stand in the forefront of the 2002 Nankai International reported in Yb3 +-doped double-clad fiber devices to get a pulse width 4. 8ns self-Q-switched output and Hybrid Q-double-clad fiber laser to get peak power greater than 8kW, the output pulse width is less than 2ns. The market share of green laser pointer is one of the comparison index.
Nankai University in 2003 reported the use of pulse peak power of 100kW pump to obtain Q-switched, and get the 60nm tunable Q-switched. November 20, 2003 reported that the Shanghai scientists have made new achievements in the laser field, the successful development of up to 107W output power fiber lasers. This laser is called "high-power ytterbium-doped double-clad fiber laser," compared with the currently available laser and its maintenance costs much lower power consumption, life is ordinary laser a few times. The group in charge of the first floor Qihong researcher told reporters, laser printing with a wide range of applications, and public life such as food directly related to the production date, security signs, etc., instead of the current terms of laser printer ink print resolution high, never fade, difficult to counterfeit, environmentally friendly, with international fashion trends. The company has provided the pictures of the featured products of green laser pointer .
