Abstract :
We develop a theoretical model for generation of second harmonics of a laser pulse in a low-density collisionless plasma through interaction of laser radiation with a THz pulse and applied external DC field. We obtain the expression for intensity of 2ω radiation which depends on the integral of THz field strength over duration of the probe pulse.
