Description
Technical field
The present invention relates to a kind of optical fiber end cap holder structure, a kind of optical fiber end cap holder structure for adaptive optic fiber collimator.
Background technology
Optical-fiber laser, with its distinctive advantage, obtains in recent years and develops rapidly, and single fiber single mode power has broken through 20kW, but still differs greatly with the MW class power of chemical laser output.For breaking through Power Limitation, optical-fiber laser multiple-beam synthesis technology is suggested and obtains broad development, is one of effective ways obtaining high power laser light output.In actual optical-fiber laser synthesis system, impact due to factors such as rigging error, error in pointing, mechanical vibration and atmospheric perturbations, the optical axis of unit light beam can offset, and causes hot spot at target effectively to overlap, thus has a strong impact on beam quality and the combined coefficient of synthesis light beam.Want to improve further beam quality and the system stability of optical-fiber laser synthesis system, it is necessary to control effectively to before inclined wave.Therefore in corresponding optical system, it would be desirable to be able to make to produce quick, the device of small angle variation light beam-controlledly.Adaptive optical fibre source collimator is with its control accuracy and controls the advantage that bandwidth is high, at home and abroad obtains extensive experimental verification.Wherein AUS laboratory is consistent with the basic structure of the adaptive optic fiber collimator that Photoelectric Technology Inst., Chinese Academy of Sciences develops, its principle is all to reach to control effect [L.A.Beresnev and M.A.Vorontsov, " the Design of adaptive fiber of outgoing beam inclined aberration in the position of collimating lens focal plane by directly controlling fiber optic tip
optics collimator for free-space communication laser transceiver,"
Proc.SPIE 5895 , 58950R , 58950R-7 (2005)].The adaptive optical fibre source collimator of this kind of structure exerts oneself the least (typically smaller than 10N) due to driver, only can drive simple optical fiber, and optical-fiber laser output end face is size is only the fibre core of tens microns, it is high that this allows for this adaptive optic fiber collimator outfan power density when bearing high power, thus more power relatively difficult to achieve output [Chao Geng, Baoyin Zhao, Entao Zhang, et al. " 1.5kW Incoherent
Beam Combining of Four Fiber Lasers Using Adaptive Fiber-Optics
Collimators," IEEE PHOTONICS TECHNOLOGY LETTERS, 25(13), 1286-1289,
(2013)].And the adaptive optic fiber collimator based on flexible hinge proposed by the National University of Defense Technology, using optical fiber end cap as outfan, reach to control the effect at collimated beam angle of inclination in the position of collimating lens focal plane by directly controlling optical fiber end cap.Optical fiber end cap is the welding quartz crystal block in optical fiber tail-end, owing to the size of optical fiber end cap is far longer than fiber core so that the power density of optical-fiber laser output end face is substantially reduced, thus is more easy to bear the output of high-power optical-fiber laser.
But it is the most immature that this NEW ADAPTIVE optical fiber collimator fixes aspect at optical fiber end cap, thus also cannot realize high-power output [Dong Zhi, Pengfei Ma,
Yanxing Ma, et al. “Novel adaptive fiber-optics
collimator for coherent beam combination,” Opt.
Express, 22(25), 31520-31528, (2014)].Thus design a kind of optical fiber end cap holder structure being applied to this adaptive optic fiber collimator and become current problem demanding prompt solution.
