Abstract

The present invention provides an external resonator light source which, by removing natural emitted light, is able to send out only light which has an extremely high wavelength purity.
As shown in FIG. 1, the present invention's external resonator light source is provided with a light amplifying element 21; a first light reflecting means 22 disposed to the side of one outgoing light edge surface 21a of the light amplifying element 21; a wavelength selecting element 23 disposed to the side of the other outgoing light edge surface 21b of the light amplifying element 21; and a second light reflecting means 24 which reflects and/or transmits outgoing light 31a from the wavelength selecting element 23, and which, together with the first light reflecting means 22, forms a light resonator; wherein outgoing light from the wavelength selecting element 23 is output as transmitted light 32 from the second light reflecting means 24.
