Ghm. Vantartwijk et D. Lenstra, NONLOCAL POTENTIAL FOR CLASS-B LASERS WITH EXTERNAL OPTICAL FEEDBACK, Physical review. A, 50(4), 1994, pp. 180002837-180002840
We report a new potential model for phase diffusion in class-B lasers
exposed to external optical feedback. Excited relaxation oscillations
cause the potential to be nonlocal. Analytical results using this new
potential agree very well with the full system dynamics. We indicate t
he experimental conditions for which the nonlocal potential becomes ma
nifest in semiconductor lasers.
