    The power dependence of a carbon-dioxide laser on the gas flow

    The gas flow rate has resulted very important to get high power in a CO2 diffusion-cooled laser. Some measurements suggest that the power dependence on the flow is connected with the chemical dissociation of the ...

    Small-signal gain of Free Electron Laser in a resonator Gaussian mode

    We present an analytical expression for the small-signal gain of a Free Electron Laser (FEL) in the presence of a Gaussian mode. To describe the electron beam evolution we use the one-dimensional (1-d) Vlasov ...

    Angular-spread effect in a free-electron laser with a nonmonoenergetic beam

    We perform analytically the calculation of the small signal gain for a free-electron laser with an electron beam having both energy and angular spread. We obtain that the gain is substantially reduced by the p...
