ABSTRACT:
A technique for automatically setting a threshold current for a laser diode which has a linear laser operating region and a lower non-linear operating region. The laser diode is controlled (1) during a warm-up period during which no operating current is supplied to the laser diode, to allow the electronics and laser diode to stabilize; (2) during an initialization period, during which the current through the laser diode is brought up to a threshold operating point above said non-linear operating region and during which no image data is applied to the laser diode; and (3) during an operating period in which digital image data is applied to the laser diode to operate it in the linear laser operating region.
