摘　　要：波导激光的光密度高,热传导性好,结构紧凑,能够实现低阈值、高功率的激光输出。光波导的制备方法有很多种,不同的制备技术各具特点,可针对不同的应用需求制备出多种结构的波导激光。离子注入作为一种成熟的材料改性技术,长期占据着波导激光制备技术的主体地位。飞秒激光是一种新型的高精技术,已经可以在激光晶体、陶瓷中实现光波导。流延成型因其膜厚度可控性强,在复合多层陶瓷的制备中得到了广泛应用,有望利用该技术获得波导结构的激光陶瓷。Waveguide lasers can achieve low lasing thresholds, high gains and high power laser outputs due to the peculiarities of high optical density, high heat transmission, and optical confinement. There are some preparation methods for optical waveguide, which have their own characteristics. According to different applications, waveguide lasers with various structures can be obtained. Ion implantation as a material modification method is an effective technique for waveguide laser among multitudinous fabrication techniques. Femtosecond laser is a novel high-precision technique, which has been used to obtain optical waveguide in laser crystals and ceramics. Tape casting, which is widely used in the preparation of composite multilayer ceramics with controllable composition layers, is a promising technique to fabricate waveguide laser ceramics.
