摘 要：This paper presents overviews of a number of processes and applications associated with high-power, high-intensity lasers and their interactions. These processes and applications include: free electron lasers, backward Raman amplification, atmospheric propagation of laser pulses, laser driven acceleration, atmospheric N2 lasing, and remote detection of radioactivity. The interrelated physical mechanisms in the various processes are discussed.
