Abstract

PURPOSE:To upgrade the utilizing efficiency of excitation light and to contrive the improvement of an energy conversion efficiency by a method wherein laser oscillation is performed using the luminescence of gas, which is generated in a penetrating hole due to discharge at the time a voltage is applied between electrodes, as the excitation light for a laser medium. CONSTITUTION:When a discharge voltage is applied between a pair of electrodes 15, Xe gas encapsulated by the discharge between the electrodes luminesces in a penetrating hole 11a and a light source for optical pumping is formed in the penetrating hole. In this case, dischargeable gas paths, which pass through the holes of supporting partition walls 13 and pass through the exterior of a laser element 11, are formed between the electrodes 15, but the paths are substantially blocked by the two supporting partition walls 13 having the small holes. Accordingly, as an excited light all passes through the interior of the laser element 11, there is no loss of the excitation light because the excitation light takes part in excitation of a laser medium. Moreover, as an exchange of glass is always performed against the heat-emission of the gas due to the luminescence and a temperature rise can be inhibited, the luminous efficiency of a lamp is also increased. As the excitation light can be generated only in the laser element, an energy conversion efficiency can be enhanced.
