Abstract: 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.

Abstract: 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.

Abstract: An information processing apparatus according to an embodiment of the present disclosure processes information about a position of an object moved by a mobile object, and includes an output unit configured to output the information about the position of the object. The information about the position of the object is obtained based on holding information indicating whether the object is held or not held by the mobile object and information about a position of the mobile object. The information about the position of the mobile object is obtained based on a captured image captured by an imaging device.

Abstract: Laser devices include a light source that emits a laser beam, an optical system that concentrates the laser beam emitted from the light source, an optical window through which the laser beam exited from the optical system passes, a housing that accommodates the optical system, and an optical window holding member fixed to the housing. The optical window holding member holds the optical window. In the first laser device, the optical window has a face or a protruding face through which the laser beam passes. When the optical window has the face, the face is flush with an edge of the optical window holding member and a film is formed on the face. When the optical window has the protruding face, the protruding face protrudes with reference to the edge of the optical window holding member and a film is formed on the protruding face.
