Abstract
A new scheme for the intracavity generation of terahertz radiation in femtosecond mode-locked Ti:Sapphire lasers is presented. The scheme combines advantages of a fast saturable semiconductor Bragg mirror with that of a photoconductive THz emitter. It significantly increases the efficiency of the intracavity THz generation. In addition, the output THz radiation can be electrically modulated at frequencies up to 100 kHz.
