Patent ID: 7822085

Claim:
A method of controlling a diode laser device which is operable to receive a control signal and to output an optical signal when the control signal exceeds a threshold value, the method comprising acts of: supplying, to the diode laser device as the control signal and at a predetermined turn-on time, a write bias signal having a value which exceeds the threshold value, wherein the threshold value is a lasing threshold for the diode laser device, and supplying to the diode laser device, as the control signal and at a predefined time before the predetermined turn-on time, a pre-bias signal, which has a magnitude that varies, is less than the threshold value and extends for a time period to immediately before the write bias signal, wherein the predefined time, magnitude, and time period of the pre-bias signal are selected to tune an output power profile of the output optical signal to a desired profile.
