Abstract :
Summary form only given: We develop a theory of terahertz Cherenkov radiation from a femtosecond laser pulse propagating as a Gaussian beam in an electro-optic medium. We show that for a fixed energy of the laser pulse there is an optimal size of the beam waist, which maximizes the terahertz yield.
