Terahertz generation with tilted-front laser pulses: Dynamical theory predicts the ways to higher terahertz yield

摘要

A dynamical theory of terahertz emission from a femtosecond laser pulse with tilted intensity front in an electro-optic crystal is developed. Applying the theory to GaAs pumped by a fiber laser and cryogenically cooled LiNbO3 pumped by a Ti:sapphire laser predicts the ways to higher terahertz yield.
