High-power adjustable pulse fiber laser

Abstract

A high-power adjustable pulse fiber laser disclosed by the present invention comprises a shell, an alarm lamp, a water pump and a fiber laser body. The top of the shell is fixedly connected with the bottom of the alarm lamp, the outer side wall of the shell is fixedly connected with a water tank, and the inner side wall of the water tank is fixedly connected with the top of the water pump. A connecting plate is fixedly connected to the inner side wall of the water tank, a water pumping pipe is fixedly connected to one end of the water pump, a fan is driven to rotate through flowing of cooling liquid in the water cooling pipe, then external air starts to enter through an air inlet, and the air pushes a cleaning plate to slide upwards. When the water pump does not work, the cleaning plate can drive bristles to clean the outer surface of the filter screen under the action of self gravity, good heat dissipation of the interior of the shell is guaranteed, when the temperature reaches a certain degree, an air pressure switch mechanism starts to work, a circuit is connected, an alarm starts to work, personnel are reminded to close the device, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a high-power adjustable pulse 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. Fiber lasers have a wide range of applications, including 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 (brazing, quenching, etc.) Water, cladding and deep welding), mi...

Problems solved by technology

[0003] When the traditional fiber laser is working, it will generate a lot of heat. If the heat dissipation effect is not good, the device will be damaged. However, the heat dissipation effect of the traditional device is not very good, and it is impossible to timely alarm when the temperature is too high. Therefore, we A high-power tunable pulsed fiber laser is proposed to solve the above problems
