Abstract

Optical parametric generation has many features such as amplification, wavelength conversion, and pulse-width narrowing due to a nonlinear propagation process. Therefore, these features are useful in obtaining broadband tunable short optical pulses.¹ We investigate the parametric propagation process by numerically solving second-order nonlinear propagation equations between three interaction fields. These calculations include the effects of depletion, transverse-mode, temporal pulse shape, walk-off, group-velocity difference, and two-photon absorption on the interaction fields simultaneously for the first time.
