Laser apparatus |
摘要 |
A laser apparatus includes a resonator and an excitation source as gain section excitation means. The resonator includes a gain section in which population inversion is obtained by optical excitation or current injection, non-gain sections in which gain with respect to a laser oscillating light beam is not positive, and two reflection mirrors. The gain section has an optical path length approximately one half that of the resonator and placed at the central portion with respect to the optical axis of the resonator. The non-gain sections are arranged on both sides of the gain section. The two reflection mirrors are arranged further outside of the non-gain sections.
