Abstract

The invention discloses a fiber laser output beam measuring device and a using method thereof, and belongs to the technical field of fiber laser measurement. The device comprises a visible light diode, a near-infrared signal light source, a pump laser, an optical fiber beam combiner, a pump beam combiner, a gain optical fiber and an optical fiber collimator, wherein the optical fiber beam combinercan combine a visible light beam emitted by the visible light diode and a near-infrared signal light beam emitted by the near-infrared signal light source into a first laser beam. A second laser cancombine the first laser beam and a pump laser beam emitted by the optical fiber beam combiner and the pump laser into a second laser beam, and the near-infrared signal light beam and the visible lightbeam pass through the gain optical fiber and then the optical fiber collimator outputs the near-infrared signal light beam and the visible light beam which are parallel to each other. The fiber laseroutput beam measuring device improves the problem that the output light beam of the laser cannot be accurately and effectively measured in the prior art.

Description

technical field [0001] The invention relates to the technical field of optical fiber laser measurement, in particular to a measurement device for an output beam of a fiber laser and a method for using the same. Background technique [0002] Fiber lasers refer to lasers that use rare earth-doped glass fiber as the gain medium. In use, the operator needs to judge the propagation direction, divergence and beam diameter of the output beam of the fiber laser. The existing spot imaging device can only measure the output beam of the fiber laser with a short transmission path. The infrared card cannot accurately measure the output beam of the fiber laser. The indicator light device installed at the output port of the fiber laser will cause the beam quality to change. SUMMARY OF THE INVENTION [0003] To this end, the present invention provides a device for measuring the output beam of a fiber laser and a method for using the same, so as to solve the problem that the output beam of...
