Abstract

The invention discloses a pulse optical fiber laser. A hollow-square-shaped heat-radiating passage is adopted, a plurality of heat-radiating fans are disposed on the front and back sides of the hollow-square-shaped heat-radiating passage, an optical fiber passive device, a power source device, a seed source and an active device are respectively mounted in the hollow-square-shaped heat-radiating passage according to size and heat-radiating requirements, a limiting wind screen is arranged in the hollow-square-shaped heat-radiating passage, and quantity of air entering each side of heat-radiating fins can be controlled by controlling sectional size of the heat-radiating fins on each side of the hollow-square-shaped heat-radiating passage and angles of the limiting wind screen. The pulse optical fiber laser has the advantages of easiness in processing, low cost, convenience for maintenance, centralized heat management, simplicity and efficiency in heat radiation, separated light and electricity, orderliness in wiring, high reliability, modularized design, convenience for system expansion and the like, and can meet working requirements of air-cooling high-power pulse optical fiber lasers under special temperature conditions.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a pulsed fiber laser. Background technique [0002] Fiber laser refers to a laser that uses rare earth element-doped glass fiber as the gain medium. Fiber laser can be developed on the basis of fiber amplifier: under the action of pump light, it is easy to form high power density in the fiber, resulting in the laser of the laser working substance. The energy level "particle number inversion", when properly added to the positive feedback loop (to form a resonant cavity), can form a laser oscillation output. [0003] Fiber lasers have a wide range of applications, and have been used in laser optical fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing rollers, metal and non-metal drilling, cutting, welding (copper Welding, quenching, cladding and deep welding), medica...
