A control method and a control system of output power control for a laser diode. The method includes utilizing a first test control signal for driving the laser diode to generate a first laser beam, detecting power of the first laser beam for generating a first detecting signal, utilizing a second test control signal for driving the laser diode to generate a second laser beam, detecting power of the second laser beam for generating a second detecting signal, determining a relationship between output power of the laser diode and a driving signal according to the first and second test control signals and the first and second detecting signals, and controlling output power of the laser diode according to the relationship. The control system includes at least a driving circuit, a sensor, and an estimator to perform the above steps.
