ABSTRACT:
A laser apparatus includes first and second laser rods disposed at both sides of a center point on an optical axis, respectively, first and second concave lenses, for compensating the first and second thermal lenses, disposed at positions which are both sides of the center point on the optical axis and inner sides of the first and second laser rods, respectively, first and second reflection mirrors disposed at positions which are both sides of the center point on the optical axis and outer sides of the first and second laser rods, respectively, a first supporting unit for supporting the first laser rod and the second concave lens such that a distance therebetween on the optical axis is kept to be a constant value, and a second supporting unit for supporting the second laser rod and the first concave lens such that a distance therebetween on the optical axis is kept to be a constant value, wherein the first and second supporting units are relatively movable on the optical axis.
