Abstract
A surface emission laser driving method according to an embodiment of the present technology includes the following two steps. (A) Generating drive pulses to be sequentially outputted to, out of a plurality of surface emission lasers disposed on a same substrate, each of the surface emission lasers selected as light-emission targets, on the basis of the number of surface emission lasers selected as the light-emission targets and a monitoring temperature that is immediately prior to light emission of each of the surface emission lasers selected as the light-emission targets. (B) Outputting the generated drive pulses to each of the surface emission lasers selected as the light-emission targets.
