本發明提供一種雙纖衣晶體光纖及其製作方法，其利用一雷射加熱基座生長法將一石榴石晶體或一藍寶石晶體之單晶棒提拉為一預定直徑之晶體光纖，將晶體光纖置入於一內纖衣玻璃毛細管中，利用雷射加熱基座生長法加熱內纖衣玻璃毛細管以軟化熔融包覆於晶體光纖之外層，而生長成一單纖衣晶體光纖，將單纖衣晶體光纖置入於一外纖衣玻璃毛細管中，利用雷射加熱基座生長法加熱外纖衣玻璃毛細管以軟化熔融包覆於單纖衣晶體光纖之外層，而生長成一雙纖衣晶體光纖，則，本發明應用在高功率雷射時，可以使用纖衣激發方式，讓高功率激發雷射耦合到內纖衣層，可有效改善高功率雷射的散熱以及效率問題。
The present invention relates to a double cladding crystal fiber and manufacturing method thereof, in which growing an YAG or a sapphire into a single crystal fiber by LHPG method, placing the single crystal fiber into a glass capillary for inner cladding, placing the single crystal fiber together with the glass capillary for inner cladding into a glass capillary for outer cladding in unison, heating the glass capillary for inner cladding and outer cladding by the LHPG method to attach to the outside of the single crystal fiber, and thus growing into a double cladding crystal fiber. When the present invention is applied to high power laser, by using the cladding pumping scheme, the high power pumping laser is coupled to the inner cladding layer, so the problems of heat dissipation and the efficiency impairment due to energy transfer up-conversion of high power laser are mitigated.
