Embodiment Construction

[0020] First describe the basic principle of the present invention in detail:

[0021] The all-fiber laser uses a low-power, long-life and low-price single wide light-emitting area multi-mode pump laser to replace the high-power multi-mode pump laser, reducing the optical power density, current density and active area operating temperature in the active area. rate is significant. Multiple low-power pump lasers are integrated into the active double-clad fiber through a laser power integrator, and an optical resonant cavity is formed between the active double-clad fibers by using a double-clad fiber grating instead of a bulk optical lens. The other one adopts the main oscillation amplification method (MOPA), which is the amplification principle commonly used in fiber amplifiers, which can strictly amplify the seed source light without changing the laser wavelength, repetition frequency, pulse width and pulse waveform. Generally, the pulse laser adopts the MOPA method, which can...

Abstract

The laser power integrator applies optical fiber laser and amplifier comprises two parts, one made of fiber beams with certain diameter, the other made of dual wrapping layer specific structure optical fiber, with one end evenly stretching coning to an integral with certain diameter tightly through heating. Treated one end of the optical beam and said dual wrapping layer optical fiber's one end fused together. The stretch coning zone needs to be controlled to proper length. In the stretching process, optical fiber needs to bear certain force of strain. The other structure it relates having the dual wrapping optical fiber surrounding evenly attached with multi mold optical beam through stretch coning, several beams of pumping light transmitted to the dual wrapping optical fiber through multi mold optical fibers.

Description

technical field [0001] The invention relates to a laser power integrator, in particular to the structure and realization method of the laser power integrator applied to fiber lasers and amplifiers or laser multiplex transmission. Background technique [0002] Fiber laser is one of the hot spots in the laser field in recent years, especially the 1.55μm wavelength fiber laser applied to the optical fiber communication window and the 1.08um wavelength high-power fiber laser used in military and industrial processing are developing more rapidly . [0003] At present, domestic and foreign industries are increasingly enthusiastic about the development and application of fiber-to-the-home (FTTH) technology. FTTH has been a dream and technology direction that people have been pursuing for 20 years, but due to obstacles in cost, technology, and demand, it is still It has not been promoted and developed on a large scale. But if the FTTH network wants to compete with the DSL widely u...
