Laser system and method for driving a laser system

A method for driving a laser system, wherein the laser system comprises:

• a laser diode configured and arranged for light emission;
• an electronic circuit configured to drive the laser diode by applying an electric drive current;
• and
• a power sensor arrangement comprising a plurality of power sensors, each power sensor configured to measure a corresponding optical power output of the laser diode,
• the method comprising:
• setting, for each power sensor of the plurality of power sensors, a target optical power output for the laser diode;
• setting a non-zero threshold value;
• applying and maintaining the electric drive current to the laser diode at a setpoint;
• measuring, at each power sensor of the plurality of power sensors, a current optical power output of the laser diode;
• comparing the current optical power output measured at each power sensor of the plurality of power sensors with the corresponding target optical power output;
• adjusting the electric drive current to a new setpoint when, for a majority of power sensors of the plurality of power sensors, an absolute value of a difference between the target optical power output and the current optical power output meets or exceeds the threshold value;
• and
• maintaining the electric drive current at the new setpoint for at least a first period.
