PURPOSE:To obtain a laser oscillator which can outputs laser light in a circular cross-sectional intensity distribution having no constricted part by using a dye laser. CONSTITUTION:A laser oscillator which causes laser oscillation by exciting pigments by making a pigment solution to flow in a circular tube 10 and irradiating the solution with light from the side face of the tube 10 and causing laser oscillation by making pilot light to incident to the solution in the flowing direction of the solution is provided with optical fibers 8 which are nearly equally arranged on the entire side face of the tube 10 and the front ends of which are fitted to the tube nearly perpendicularly to the axis of the tube 10. |
