ABSTRACT:
A laser diode driver with automatic power control in which start-up characteristics are controlled to avoid unsafe power levels at a driven laser is disclosed. The laser diode driver according to the invention produces a bias control signal that controls a bias current source such that the bias current supplied to the laser is maintained below a predetermined level during a start-up period.
