提出了在飞秒锁模钛宝石激光器腔内产生太赫兹辐射的新设计方案,并给出了太赫兹产生器件的结构参数以及器件的设计原理。新设计的器件把光电导太赫兹偶极天线发射器与飞秒钛宝石激光器的可饱和Bragg反射镜结合在一起,不仅可以提高太赫兹辐射的产生效率,而且可以使飞秒钛宝石激光器自启动锁模.
A new structure of an intracavity generator of terahertz(THz) radiation in the cavity of femtosecond mode-locked Ti : Sapphire lasers was presented. The scheme combines advantages of a fast saturable semiconductor Bragg mirror with that of a photoconductive THz emitter. It will significantly increase the efficiency of the intracavity THz generation, as well as self-start the mode-locked of femtosecond Ti : sapphire lasers.
