| 摘要 | A laser light source includes an optical resonator and a first optical filter. The first optical filter is provided outside the optical resonator, and does not constitute an optical resonator structure. For example, antireflection coating is performed on the optical resonator side of the first optical filter and on a surface on the opposite side thereto, and a reflection structure in which light after passing through the first optical filter is reflected in the direction to the optical resonator is not present on an optical path of the light. | ||

| 主权项 | 1. A laser light source, comprising: an optical resonator; a first optical filter, provided outside the optical resonator, which does not constitute an optical resonator structure; and a second optical filter provided inside the optical resonator, wherein the laser light source is devoid of any optical elements being placed between the optical resonator and the first optical filter, wherein one of a plurality of longitudinal modes of the optical resonator passes through the first optical filter, and wherein light which passes through the first optical filter is output to an outside of the laser light source. | ||
