How Does Cnc Fiber Laser Machine Work?

CNC Fiber Laser Machine works principle: it is to increase an energy detection device in the back-end Cnc Laser generator, and compared the signal with the theoretical value. Forming a negative feedback through a closed-loop optical transmission cnc lazer power control system to achieve precise control purposes laser energy output optical Fiber Laser cuttingmachine  pulse energy output in real-time online monitoring, the instability of the laser pulse output energy control in ± 2 %. The stability of output energy is an important parameter for ultra-short Cnc Fiber Laser Cutting Machine.

Cnc Fiber Laser power generator by the fiber laser pump source, couplers, rare earth doped fiber, and other components constituting the resonant cavity. Pump source is one or more high-power laser diode array of pumping its light emitted by a special pump structure coupled into rare earth doped fiber as the gain medium, the pump wavelength photons are absorbed by the doped fiber media form population inversion, stimulated emission of light by the mirrors of the resonator and the oscillation feedback form laser output. Fiber Laser Machine with fiber as a wave guide medium, high coupling efficiency, easy to form a high power density, cooling effect, without the huge refrigeration system with high conversion efficiency, low threshold, beam quality and narrow line width and other advantages. Moreover, Fiber laser machine power generator without optical lenses, with adjustment-free, maintenance-free, high stability advantages; long working life and maintenance-free time, the average maintenance time in more than 100,000 hours.

Pump light emitted by the pump source by the side mirror coupled into the gain medium, since the gain medium is a rare earth doped optical fiber, thus pumping light is absorbed, absorbed photon energy level transitions of rare earth ions and achieve population inversion, particle reversed through a resonant cavity, the transition from the excited state to the ground state, energy is released, and the formation of a stable laser output.
