The advantages of fiber lasers. Fiber laser as a representative of the third generation of laser technology, has the following advantages: (1) glass fiber, low manufacturing cost, the advantages of miniaturization, intensification of the technology is mature and can spare fiber; (2) glass fiber on the incident pump light does not need that as the crystal strict phase matching, which is due to the Stark splitting of a glass substrate due to non-uniform broadening caused by absorption with a wide sake; (3) of the glass material has a very low volume area ratio, fast heat dissipation. low loss, high on the conversion efficiency, low lasing threshold. It is based on the basic function of the common   green laser pointer   .
The output laser wavelength: This is because the rare earth ion energy levels are very rich in its variety of rare earth ions; (5) Tunable: broad fluorescence spectrum due to the rare earth ion energy level width and glass fiber. (6) fiber laser cavity optical lenses, adjustment-free, maintenance-free, high stability of the advantages of conventional lasers can not match. (7) fiber exported, making the laser can be easily qualified for a variety of multi-dimensional arbitrary space processing applications, the mechanical system design is very simple. (8) qualified for the poor working conditions, has a high tolerance for dust, shock, shock, humidity, temperature. (9) without thermoelectric cooling and water cooling, just a simple air-cooled. This kind of   usa green laser pointer    is called the wireless presenter laser pointer.
High electro-optical efficiency: an integrated electro-optical efficiency of up to 20% or more, significant savings in power consumption at work, saving operating costs. (11) high power, the commercialization of the fiber laser is six kilowatts. High-power fiber lasers and cladding pump technology. Double-clad fiber is undoubtedly a major breakthrough in the field of optical fiber, which makes the production of high-power fiber lasers and high-power optical amplifiers become a reality. Since 1988 E Snitzer is the first description of a cladding-pumped fiber laser cladding-pumped technology has been widely applied to fiber lasers and fiber amplifiers, as the production of high power fiber lasers the preferred way to. Cladding pumping technology, consists of four levels: (1) fiber core; ② The inner cladding; ③ outsourcing layer; ④ protective layer. The wireless presenter   green laser pointer    can also be called as the wireless presenter.
The pump light coupled into the inner cladding (inner cladding is generally shaped structure, oval, square, plum-shaped, D-shaped hexagon, etc.), including cladding and outsourcing layer in the light (general design for the round) between bounces back and forth several times through the single-mode core absorption. The fiber of this structure does not require the pump alone, single-mode lasers, and fiber length pumped, so the choice of high-power multimode laser diode array pump source, will be more than about 70% of pump energy indirectly coupled to the core, greatly improving the efficiency of the pump. Cladding pumped technical characteristics of such lasers have the outstanding performance of the following aspects. 1) high-power multimode pump diode modules can be radiated out 100 watts of optical power. This kind of   green laser pointer    can be designated as the wireless presentation controller and PPT presenter.
Multiple multimode pump diode parallel set, you can allow the design of high power output of fiber lasers. 2) do not need the wide surface of the thermoelectric coolers such a high-power multimode diode high temperature, simply air-cooled, low cost. Activity within a wide pump wavelength range of high-power fiber lasers cladding optical fiber doped with erbium / ytterbium rare earth elements, there is a wide, flat and because of the light wave absorption (930-970nm), diode pumped without any type of wavelength stabilization device 4) high efficiency pump light several times across the single-mode fiber core, so its high utilization rate. The wireless presenter   green laser pointer    can be divided into two kind of laser pointer according to the adopted frequency technology.
