Zusammenfassung:To provide a solid-state laser crystal micronized structure which enables heat conductivity/light-resistant strength/unit length lase gains unique to a solid-state laser to be acquired while acquiring beam quality equal to that of a fiber laser, and to provide a method for manufacturing the same.SOLUTION: A crystal solid-state laser medium composite comprises: a crystal solid-state laser medium; and a high heat conductive material approximately similar in thermal expansion coefficient to the crystal solid-state laser medium. The crystal solid-state laser medium and the high heat conductive material are joined. A method for manufacturing the crystal solid-state laser medium composite at least includes a joining step of joining a reinforcement material to the crystal solid-state laser medium, and a polishing step of polishing the crystal solid-state laser medium and the reinforcement material together.SELECTED DRAWING: Figure 1 【課題】ファイバーレーザー並みのビーム品質を得ながら、固体レーザーならではの熱伝導率・耐光強度・単位長レーザー利得を得ることのできる、固体レーザー結晶の細化構造、及びその製造方法を提供することを課題とする。【解決手段】結晶型固体レーザー媒質と、前記結晶型固体レーザー媒質と熱膨張係数が近似した高熱伝導材とから成り、前記結晶型固体レーザー媒質と前記高熱伝導材とが接合していることを特徴とする結晶型固体レーザー媒質であり、結晶型固体レーザー媒質に補強材を接合する接合工程、接合された結晶型固体レーザー媒質と補強材を共に研磨する研磨工程、を少なくとも含むことを特徴とする結晶型固体レーザー媒質の製造方法により得られる。【選択図】 図1
