Abstract
When irradiating laser beam from the side face of the capillary array, an optical axis of the laser beam is inclined in vertical direction with respect to a plane face formed by the capillary array, thus, reflection light by the capillary array and returning light is prevented from entering into a laser beam source, thereby, instability of laser oscillation is eliminated.
