Abstract

PURPOSE:To unnecessitate coating treatment on the reflection plane by a method wherein total reflection is performed on the reflection plane by making an inclination between the incidence plane and the reflection plane and between the emission plane and the reflection plane. CONSTITUTION:With respect to a laser medium 1, an excitation lamp 2, an incidence plane 3, an emission plane 4, and a reflection plane 5; thetain is the angle of incidence, thetaout the angle of refraction, alpha the angle made between the incidence plane and the reflection plane and between the emission plane and the reflection plane, n2 the refractive index of the laser medium 1, n1 and n2 the refractive indices of the substance in contact with the laser medium, and broken lines the region of laser beam advancement. A laser beam comes into the incidence plane 3 at the angle of thetain and comes into total reflection on the reflection plane 5 when satisfying Formula 1. For example, in the case of a laser medium of n1=n3=1, n2=1.52, alpha=26.65 deg., when made incident at thetain=56.65 deg., a laser beam is reflected on the reflection plane 5 at a reflection angle of 60 deg..
