Light source, optical pickup, and electronic apparatus

A fabrication method of a light source comprising the steps of:

• providing a semiconductor light emitting device which has a light emitting face and emits light from a part of the light emitting face;
• providing a container which has a light transmitting window for transmitting the light and accommodates the semiconductor light emitting device;
• accommodating the semiconductor light emitting device in the container, thereby blocking the semiconductor light emitting device from the air;
• and
• performing gettering of a material containing at least one of carbon and silicon, by irradiating with light a region that is positioned in the container, and the region being positioned other than the part of the light emitting face of the semiconductor light emitting device.
