Abstract

A semiconductor laser driver to drive at least one semiconductor laser, the semiconductor laser including a storage device, an emission-intensity setting device, and a drive circuit. The storage device stores emission-intensity switching data to control light-emission intensity of the semiconductor laser, the emission-intensity setting device sets the light-emission intensity based on the emission-intensity switching data stored in the storage device, and, the drive circuit generates a driving current to drive the semiconductor laser based on the light-emission intensity set in the emission-intensity setting device.
