Abstract

A laser control device comprises a driver circuitry for supplying a drive current to a laser diode (LD). The device further comprises a digital storage for storing drive current values for a plurality of temperature conditions, and a central processing unit coupled to the digital storage for controlling the driver circuitry in accordance with the drive current values from said digital storage. The central processing unit is configured for multiple updating the drive current values stored in the digital storage.
