Fiber laser on-line monitoring system

Abstract

The invention provides an optical fiber laser on-line monitoring system. The system comprises a mounting frame, a laser generating part, an optical fiber sampler, a left side transmission optical fiber, a right side transmission optical fiber, a laser output head, an end detection unit, a middle detection unit, a signal processing circuit and a data processing and collecting unit, wherein the laser generating part, the optical fiber sampler and the end detection unit are sequentially mounted on the upper side of the mounting frame from left to right; the left side transmission optical fiber is inserted into the left side of the optical fiber sampler, and meanwhile, the left side transmission optical fiber is in contact with the laser generating component; and the right side transmission optical fiber is inserted into the right side of the optical fiber sampler. The lifting handle is installed on the upper middle portion of the protective cover through screws so that a user can conveniently hold the lifting handle to lift the protective cover during use; and the damping spring is arranged between the inner side L-shaped plate and the outer side L-shaped plate so that a damping protection effect can be achieved on the monitoring equipment when the monitoring equipment is lifted during use.

Description

technical field [0001] The invention belongs to the technical field of fiber laser monitoring, and in particular relates to an online monitoring system of fiber laser. Background technique [0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that acts as a means of light transmission. The transmission principle is "total reflection of light". Fiber laser (FiberLaser) refers to a laser that uses a rare earth-doped glass fiber as a gain medium. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, high power density is easily formed in the fiber, resulting in laser operation. The laser energy level of the material is "particle number inversion", and when properly added to the positive feedback loop (to form a resonant cavity), the laser oscillation output can be formed. [0003] However, the existing fiber laser online monitoring system does not have the flexibility to carry the monitoring equipment ac...
