WebJul 25, 2024 · A kinetic (or maser) instability applies when the imaginary part of the response function is included and leads to negative absorption. Maser growth requires that the growth rate be less than the bandwidth of the growing waves. Phase mixing then occurs faster than wave growth, implying that the random phase approximation (RPA) applies.
