Gain Properties of Rod Amplifier with Non-Imaging Reflector
Rod amplifier with non-imaging reflector is designed based on the edge-ray principle. Under the same flashlamp electrical power and rod dimensions, the stored energy density and the small-signal gain coefficient of Nd∶glass rod amplifier with non-imaging and imaging reflector are simulated, respectively. The numerical simulated results are consistent with the experimental results. The non-imaging reflector can reflect all the xenon flashlamp rays to the Nd∶glass rod surface, which can enhance the photoelectric conversion efficiency, reduce the generation of waste heat, increase the pumping efficiency and the amplifier′s gain property. This design can achieve considerable cost savings and improve the efficiency of the amplifier.
