具有同轴泵浦灯和磷酸盐玻璃激活元件的高效量子管目前极为关注使法玻璃激光器达到极限能量效率的可能性’‘－‘’。这种可能性与“光锅炉”原理的实现有关，须建立激活元件最大限度全部吸收泵浦灯辐射的条件。在自由振荡状态下，对于具有管形磷酸盐激活元件的系统，实验... High-efficiency quantum tubes with coaxial pump lamps and phosphate glass activation elements are currently very much concerned with the possibility of reaching the ultimate energy efficiency of the lasing glass laser. This possibility is related to the realization of the principle of a “light boiler”, and the conditions for maximizing the absorption of the pump light by the activating components must be established. In a freely oscillating state, for systems with tubular phosphate activation elements, experiments ...
