摘要: A pulsed electromagnetic-wave generator includes an excitation light source, a laser resonator, a pulse generating unit, and a wavelength converting unit. Excitation light from the excitation light source enters the laser resonator. The pulse generating unit is configured to generate a pulsed light group including at least two or more pulses with different frequencies (ω) and different oscillation timings (t) in one excitation process of the excitation light source, an oscillation frequency difference (Δω) between the pulses in the pulsed light group being an integral multiple of a Free Spectral Range (FSR) of the laser resonator. The pulsed light group enters the wavelength converting unit. The wavelength converting unit is configured to generate a pulsed electromagnetic wave in which a wavelength of each pulse in the pulsed light group is converted.

摘要: A light source device includes a light source and a projection optical system. The light source includes a plurality of light emitters. The projection optical system is configured to emit light emitted from the light source. A light emission amount per unit area in a light emission region of the light source corresponding to an irradiated region where a magnification of the projection optical system is relatively large, is larger than a light emission amount per unit area in a light emission region corresponding to an irradiated region where a magnification of the projection optical system is relatively small.
