Abstract

PURPOSE:To eliminate temperature dependency of oscillation wavelength, in a laser device consisting of a laser medium, a resonator and a resonator supporting body, by making an arrangement to compensate for thermal expansion coefficient and length of the supporting body, reflectivity and length due to variation of the medium temperature, and fluctuation of oscillation wavelength due to the variations. CONSTITUTION:A resonator supporting body 4 is composed of SiO2 or invar whose thermal expansion coefficient is small, and a resonating plate 4' is attached to one end of the body. A laser medium 1 having an electrode 3 on its surface is provided on the other end opposite to this, and on the surface opposite to the resonating plate 4' of the medium 1 a reflection preventing surface 6 is provided to prevent reflection caused by difference in reflectivity between the medium 1 and air. And on the surface opposite to the surface 6 of the resonating plate 4', a light-reflecting surface 5 is provided to constitute a resonator between the surfaces 2' and 5. In such a constitution, when temperature coefficient of the supporting body 4 is minus and length of the medium 1 is t, length 1 of the supporting body 4 excluding the resonating plate 4' is prescribed to be approximately 6 times of t.
