The rate of absorption and emission of radiation is calculated for two laser fields interacting with a homogeneously broadened, three-level molecular system. The time-dependent Schrodinger equation is utilized in the density matrix formalism, with the laser fields treated classically. These fields operate at frequencies wp and w,, being off resonance by Sp and S6, respectively, and the analysis allows arbitrary values of field strength while considering each field's resonance conditions. Analytic expressions are derived for the imaginary part of the electric susceptibility, x"(wp) and y(w,). This work expands upon previous calculations by accommodating arbitrary values for the field strengths. Through computer evaluation, properties of the solutions for x"(wp) and ~"(w,) are examined, distinguishing between single-photon and two-photon (Raman) contributions. Additionally, conditions for optimizing dl(w,)/dz and the photon conversion efficiency are presented, providing relevant conclusions for the application of results to analyze pulsed, optically pumped submillimeter lasers and studying two-photon absorption in gases.
