... If the system has a gain coefficient above this value, one photon will be enough to start the process, and since one photon is always around, the system will then start to produce light on its own without outside help. Since the gain coefficient is a strong function of the carrier density, this also ...

... ponderomotive force can be beneficial in particle acceleration by a laser pulse [2]. Also, the use of relativistic 10μm pulses allows one to probe overdense plasma in the plasma density range of ne=1-100ncr (where ncr=1.1x1021/λ2[μm]cm-3) using visible frequency probes.
