The time evolution of atomic response in an open Λ-type particle-free inverted laser system is studied, and the mechanism of the particle-free inverted optical amplification is illustrated. It is found that the time evolution of the atomic response in an open system is similar to that of the closed system The significant difference is that the change of oscillation frequency and the non-harmonic oscillation in time evolution come from the random coherence of atomic oscillator in the system.
