摘要	A system for removing waste energy in the form of sensible heat and fluorescent energy from a solid state laser medium having a broad surface. The system includes a manifold disposed about the laser medium having a plurality of inlet jets interspersed with a plurality of exhaust orifices. Coolant fluid is circulated through the manifold. The fluid is forced through the plurality of inlet jets to impinge the broad face of the laser medium, thereby transferring waste energy by convection from the laser medium to the coolant fluid. The coolant fluid is further circulated to exhaust the pumphead manifold through the plurality of exhaust orifices. The fluorescent energy, which is radiated from the laser medium, is converted to sensible heat by an absorber disposed within the coolant adjacent to the laser medium. The coolant then removes the converted heat by forced convection. The absorber can be suspended particles in the coolant fluid or a porous material supported in the manifold at some distance from the laser medium.
其他摘要	一种用于从具有宽表面的固态激光介质中去除显热和荧光能量形式的废能的系统。该系统包括围绕激光介质设置的歧管，该歧管具有散布有多个排气孔的多个入口喷嘴。冷却液通过歧管循环。迫使流体通过多个入口射流以冲击激光介质的宽面，从而通过从激光介质到冷却剂流体的对流传递废能。冷却剂流体进一步循环以通过多个排气孔排出泵头歧管。从激光介质辐射的荧光能量通过设置在与激光介质相邻的冷却剂内的吸收器转换成显热。然后冷却剂通过强制对流除去转化的热量。吸收器可以是冷却剂流体中的悬浮颗粒或者在与激光介质一定距离处支撑在歧管中的多孔材料。
