Abstract
Digital control of actively mode-locked lasers where an active feedback control system is implemented to include a digital processor such as a microprocessor. The digital processor digitally extracts noise information from multiple monitor signals generated from the laser output and digitally diagnoses the operating condition of the laser based on the noise information. Based on the operating condition of the laser, the digital processor generates control signals to adjust the laser cavity to establish or regain the mode locking condition and to maintain the mode locking by reducing the output noise.
