A study was performed to determine the performance of a wideband chirp-driven waveguide amplifier. Included in the study are the closed-form solutions of the rate equations with a chirped input, the calculation of the frequency errors generated by dispersion and the necessary waveform needed to overcome dispersion and thirdly the effects of a saturation and a nonuniform susceptibility profile across the aperture of the waveguide on the mode quality. The topics discussed in detail are: 1. The absence of saturation-induced power broadening of the amplifier bandwidth in fast chirped radar applications. 2. The excellent mode discrimination properties in waveguide devices, particularly when compared to the more conventional free-space device. 3. The mechanisms that cause degradation in performance of waveguide amplifiers in laser radar applications.
