Abstract
A semiconductor light emitter includes a substrate, a semiconductor multilayer structure including a light emission unit that emits light in an oblique direction with respect to the substrate, a base on which the substrate is disposed, a holding member that holds the substrate at an angle set in advance with respect to the base, a temperature control unit disposed parallel to the substrate to adjust a temperature of the substrate, and a shaping optical system held against the substrate to shape a luminous flux emitted from the semiconductor multilayer structure.

A semiconductor light emitter comprising:
- a substrate;
- a semiconductor multilayer structure including a light emission unit that emits light in an oblique direction with respect to the substrate;
- a base on which the substrate is disposed;
- a holding member that holds the substrate at an angle set in advance with respect to the base;

- a shaping optical system held against the substrate to shape a luminous flux emitted from the semiconductor multilayer structure.
A semiconductor light emitter comprising:
- a substrate;
- a semiconductor multilayer structure including a light emission unit that emits light in an oblique direction with respect to the substrate;
- a base on which the substrate is disposed;
- a holding member that holds the substrate at an angle set in advance with respect to the base;
- and
- a temperature control unit disposed parallel to the substrate between the holding member and the substrate or on a substrate side of the holding member to adjust a temperature of the substrate.
A light output apparatus comprising:
- a substrate;
- a semiconductor multilayer structure including a light emission unit that emits light in an oblique direction with respect to the substrate;
- a base on which the substrate is disposed;
- a holding member that holds the substrate at an angle set in advance with respect to the base;
