摘要
The nonequilibrium nanoplasma created by irradiation of a cluster, or other nanosystems such as large molecules, with an intense infrared-laser field may be used as an amplifying medium for a high-frequency probe field. We employ a simple description where the nanosystem is modeled by particles bound by a self-consitent potential. An incident probe field suffers gain or loss depending on the respective parameters by a mechanism that is usually referred to as collisionless damping. The model is simple enough to allow for an essentially analytical solution.
