| 摘要 |
The present invention can control output of pulses from a semiconductor laser. In the present invention, a short-pulse light source (1) applies a laser drive voltage (DJ) having a pulse-shaped drive voltage pulse (DJw) to a semiconductor laser (3), thereby causing the semiconductor laser (3) to emit specific output light (LAp), as laser light (LL), having a pulse-shaped specific peak (APK) and a specific slope (ASP), an emission intensity of the specific slope (ASP) being lower than an emission intensity of the specific peak (APK). The short-pulse light source (1) controls a voltage pulse half-width (Thalf), which is a pulse width of the drive voltage pulse (DJw), by setting a pulse width (Ws) of a set pulse (SLs), thereby adjusting a ratio between the specific peak (APK) and the specific slope (ASP).
