Abstract
An optical system includes an electrically pumped laser light source and an optically pumped laser light source. An optical switch is located in a light path of the electrically pumped laser light source such that when the optical switch is in a first position light from the electrically pumped laser light source is directed toward the optically pumped laser light source and when the optical switch is in a second position light from the electrically pumped laser light source is directed away from the optically pumped laser light source.
