Abstract: Directed to freely adjusting an emission period of a semiconductor laser.In the present invention, pulsed light serving as pulse-shaped laser light (LL) is emitted from a semiconductor laser (3), and a laser drive voltage (DJ) that is generated on the basis of a pulse signal (SL) and that has pulse-shaped drive voltage pulses (DJw) is applied to the semiconductor laser (3). At this time, a short-pulse light source (51) varies a voltage period (TV) corresponding to an interval between the drive voltage pulses (DJw), thereby varying a set period (TS) corresponding to an interval between generated signal pulses (SLw) in the pulse signal (SL).
