  • Abstract
    Transient behaviors in which the output power amplified through the fast-axial-flow (FAF) CO2 laser amplifier decreases temporally after initiating the discharge are discussed. The output power becomes stable within a few minutes, i.e. the transient time. These phenomena should strongly depend on input irradiance, plasma length, gas-flow velocity v, and discharge current I dis. The small signal gain γ0 is formulated as a function of v and Idis and the discharge time for a partially-homogeneously-broadened, slightly saturated gain medium at individual vibrational-rotational transitions
