Abstract:
The present invention discloses a method for reducing a self-mixing interference effect of a laser system, comprising the following step: connecting a direct current (DC) bias circuit and a modulated signal generator to electrodes of a laser, respectively. The DC bias circuit is configured to drive the laser and provide carriers for pumping to the laser; a resonant cavity is provided in the laser, and is configured to convert the carriers for pumping into photons which are subjected to stimulated radiation to form stable laser output; the DC bias circuit and the modulated signal generator are injected into the laser; the modulated signal generator outputs a modulated signal; and the modulated signal matches a parasitic parameter of the laser so as to change the distribution state of the photons in the resonant cavity of the laser. The present invention spatially and temporally reduces power fluctuation of a laser within a short period of time caused by the self-mixing interference effect, ensures the stability of the whole laser system, and has the advantages of low cost, easy assembly and adjustment, and stable performance.

Claim (Index 4):
The method for reducing a self-mixing interference effect of a laser system according to  claim 1 , wherein an optical element ( 4 ) configured to guide the light beams and/or shape the laser beams is disposed behind the laser ( 1 ) at an interval.
