Various systems and methods are provided for biasing a laser. In one example, a feedback circuit establishes a bias current in a laser. A stabilizing capacitor is coupled to the feedback circuit, the stabilizing capacitor slowing the response of the feedback circuit to a feedback input. A capacitor charging circuit is included in the feedback circuit. The capacitor charging circuit is activated upon a start-up of the feedback circuit to charge the stabilizing capacitor. Thereafter, the capacitor charging circuit is deactivated when a charge on the stabilizing capacitor reaches a predefined charge threshold.
