Claim Text:
1. A laser diode driver comprising: a first current source configured to generate one or more bias current pulses; a second current source configured to generate one or more drive current pulses; a controller configured to operate the first current source to generate a first bias current pulse and to operate the second current source to generate a first drive current pulse; and a summer having inputs to receive the one or more bias current pulses and the one or more drive current pulses, and having an output terminal configured for connection to a laser diode, the summer configured to drive the output terminal with an output current that is the sum of the bias current pulses and the drive current pulses, wherein the first drive current pulse has a rising edge that is delayed in time relative to a rising edge of the first bias current pulse by the time period T
