Abstract:
1. A coherent light source apparatus comprising: a first optical system, which comprises a first light emission region formed by a coherent light source, wherein light is projected from the first light emission region to form a second light emission region; a light deflection unit, that deflects light flux relating to formation of the second light emission region near the second light emission region; a second optical system, that is disposed downstream of the light deflection unit and forms a third light emission region that is conjugate to the second light emission region; and a light mixing unit that is disposed downstream of the second optical system, the light mixing unit mixes components of an angle and a position of an incident light, wherein an incident end of the light mixing unit is provided near the third light emission region, wherein the light deflection unit is configured to perform an operation for continuously changing a direction in which the light flux is deflected.
