title: Voltage-controlled intracavity terahertz generator for self-starting Ti:sapphire lasers.
abstract: A new, efficient, intracavity scheme for terahertz generation in femtosecond mode-locked Ti:sapphire lasers is proposed and demonstrated. The terahertz radiation is generated by a transient photocurrent in a GaAs layer grown on a fast semiconductor saturable absorber mirror. The average terahertz output radiation power is voltage controlled and can be electrically modulated at frequencies up to 100 kHz.
