We examine here the effects of plasmas and beam slippage on the gain of an optical klystron (OK) free electron laser (FEL) device under the influence of a weak guiding magnetic field and background plasma. The beam energy spread decreases with background plasma density n_op and increases with beam plasma density n_ob. The maximum gain (G_max) scales proportional to a6001c861669eba"">. The beam slippage phase Δψ scales directly to five power of relativistic factor γ₀ and one half power to n_ob.
