Abstract
A laser apparatus includes a resonator and an excitation source for gain section excitation. The resonator includes a gain section in which a 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 centrally with respect to the optical axis of the resonator. The non-gain sections are arranged on opposite sides of the gain section. The two reflection mirrors are arranged further beyond the non-gain sections.
