Optical device and distance measuring device

Abstract

An optical device and a distance measuring device capable of appropriately detecting an emission timing of oscillation light are provided. An optical device according to the present disclosure includes: a light emitting element including a semiconductor section that is included in a first resonator causing light of a first wavelength to resonate and causes the light of the first wavelength to oscillate, a solid-state laser medium that is included in the first resonator and a second resonator causing light of a second wavelength to resonate and causes the light of the second wavelength to oscillate, and a saturable absorber included in the second resonator and emitting the light of the second wavelength; a detector detecting the light of the first wavelength or a drive current of the light emitting element; and an emission timing detecting unit detecting an emission timing of the light of the second wavelength on the basis of a detection result of the light of the first wavelength or the drive current of the light emitting element acquired using the detector.
