Abstract[English]
The present application relates to the technical field of laser devices, and discloses a multi-bar series assembly and a pumped solid-state laser. The multi-bar series assembly comprises a plurality of bar modules which are arranged. Two adjacent bar modules are spaced apart from each other, and a bent and deformable metal foil is connected between the two adjacent bar modules. Positive and negative electrodes of the two adjacent bar modules are electrically connected by means of the metal foil connected between the two adjacent bar modules. By means of the method, the present application allows for effective release of thermal stress in the multi-bar series assembly, eliminates the problem of laser bar cracking caused by use of a hard connection in a conventional structure, improves structural reliability and stability, and prolongs service life.[French]
La présente demande se rapporte au domaine technique des dispositifs laser, et concerne un ensemble série à barres multiples et un laser à solide pompé. L'ensemble série à barres multiples comprend une pluralité de modules de barre qui sont agencés. Deux modules de barre adjacents sont espacés l'un par rapport à l'autre, et une feuille métallique courbée et déformable est raccordée entre les deux modules de barre adjacents. Des électrodes positive et négative des deux modules de barre adjacents sont électriquement connectées au moyen de la feuille métallique raccordée entre les deux modules de barre adjacents. Au moyen du procédé, la présente invention permet une relaxation efficace de la contrainte thermique dans l'ensemble série à barres multiples, élimine le problème de fissuration de barre laser provoquée par l'utilisation d'une connexion dure dans une structure classique, améliore la fiabilité et la stabilité structurales, et prolonge la durée de vie.[Chinese]
本申请涉及激光器件技术领域，公开了一种多巴条串联组件及泵浦固体激光器，该多巴条串联组件包括排列设置的多个巴条模块，相邻两个巴条模块相互间隔设置，且相邻两个巴条模块之间连接有弯曲且可形变的金属箔，相邻两个巴条模块通过连接在二者之间的金属箔实现正负极导电。通过上述方式，本申请能够有效释放多巴条串联组件中的热应力，消除传统结构采用硬连接带来的激光巴条开裂的问题，提升其结构可靠性和稳定性，延长使用寿命。
