Abstract
A method of controlling a laser unit in order to negate heat build-up caused by a laser modulation current, and eliminating artifacts caused by image related thermal effects. Upon receipt of an activation signal, an activation current is applied which causes lasing of the laser unit. Upon receipt of a deactivation signal, the method ceases lasing by selectively applying either an idle current below the activation current, or a cooling current below the idle current.
