ABSTRACT:
A drive circuit for a semiconductor light emitting element used for a light source device adapted to output a laser beam converted using a wavelength conversion element adapted to generate a second harmonic wave, includes a switching element connected to a power supply, an inductor having one end connected to the power supply via the switching element, and the other end connected to the ground, a first terminal disposed between the switching element and the inductor, to which a cathode terminal of the semiconductor light emitting element is connected, and a second terminal disposed between the other terminal of the inductor and the ground, to which an anode terminal of the semiconductor light emitting element is connected.
