PURPOSE: A single body apparatus for pumping variable divergence reflectors is provided to prevent a loss of pumped light due to a crevice at both end portions of an optical system by coating or vaporizing the end portions. CONSTITUTION: A single body pumping container(6) for variable divergence reflector includes a laser gain medium(2) having a predetermined shape at a concentric portion thereof. A gain medium fixing plate is implemented at both ends of the laser gain medium. A thermal capacity of the laser gain medium is varied by applying a soluble crystal or a refractive glass material on the laser gain medium. A cooling line(8) is implemented on an inner diameter of the laser gain medium. A parabola shape is generated by simulated data obtained by using an optical tracking technique to maximize a pumping distribution outside of the laser gain medium. A surface of the parabola shape is high-reflection coated or a predetermined material is vaporized thereon. A variable divergence reflective surface, having a size determined according to a pumping density, the size of the laser gain medium, and characteristics of the generated laser beam, is formed. An optical system is formed to prevent feedback of an excitation diode laser. Both ends of the optical system are formed to have a round shape.
