Abstract:   (3394 Views)
Amplification of ultrashort chirped laser pulses, through a non-collinear optical parametric scheme, is investigated in small-signal gain and saturation regimes. By solving the non-linear interaction coupled equations in both regimes it is shown that the signal beam intensity increases exponentially with respect to the interaction length, whereas saturation is observed in the second pass which is followed by depletion of pump beam energy. Based on the parameters obtained from analytical calculations, a two-stage NOPCPA system is proposed, which is expected to increase the signal energy from 5 nJ to 38μJ, with a gain of about 106 .
Keywords: nonlinear interaction, phase-matching, optical parametric, Chirp, Non-collinear geometry
