摘要：

Simple expressions for the mode-locked pulses induced by either intracavity phase or amplitude (FM or AM) modulation in a homogeneous laser are developed by following a Gaussian pulse through one pass around the laser cavity. The predicted pulsewidth in either case is τp ∼ (g 0/δ)1/4 × (ΔfaxialΔ fatomic)-1/2, where g0 = saturated single-pass excess laser gain, δ = single-pass modulation index, Δf axial = axial mode spacing, and Δfatomic = atomic linewidth. The FM case also shows a frequency 'chirp' equal to the pulsewidth. Experiments with the FM case in a Nd:YAG laser show excellent agreement with the analysis. © 1969 The American Institute of Physics.
