Product Introduction

The pump light generated by the pump is coupled to the gain medium through a mirror. Because the gain medium is rare earth doped fiber, the pump light is absorbed. The rare earth ions that absorb photon energy undergo energy level transition and realize particle number inversion. After inversion, D particles pass through the resonant cavity, transition back to the ground state from the excited state, release energy and form a stable laser output.

The structure of fiber laser is similar to that of traditional solid-state laser and gas laser. It is mainly composed of pump source, gain medium and resonant cavity. Among them, the pump source is generally a high-power semiconductor laser, the gain medium is rare earth doped glass fiber, and the resonator is composed of coupler or fiber grating.

Fiber laser, English name fiber laser, is a device that uses rare earth doped glass fiber as gain medium to generate laser output. The fiber laser can be developed based on the fiber amplifier. Because the fiber core in the fiber laser is very thin, under the action of pump light, the internal power density of the fiber is high, resulting in the phenomenon of "particle number inversion" of the laser energy level. On this basis, the laser oscillation can be formed at the output by forming a resonant cavity through a positive feedback loop.
