Abstract

The present disclosure provides a laser power correction method, device, and laser for suppressing relaxation oscillation. The method includes: setting the laser to a first duty cycle and a first frequency, adjusting current so that the average power is a preset power, and recording the present current value; adjusting the frequency so that the average power is the preset power, recording all frequency values to obtain a frequency interval; changing the duty cycle to obtain frequency intervals at various duty cycles; setting the laser to a second duty cycle and the representative frequency, adjusting the current so that the average power is the minimum/maximum average power, recording the minimum and maximum currents, and determining a current-average power relationship; changing the duty cycle to obtain the current-average power relationship at various duty cycles and in different frequency intervals. The present disclosure is applicable to a pulsed laser control method that adds a small step signal to suppress relaxation oscillation. The current-average power relationship is determined by actually measuring the power output value, thereby achieving accurate correction of the laser.
