Steady-state mode-locking operation in a laser with a saturable absorber

It is shown that a simple correspondence exists between the form of radiation for a steady-state mode-locking operation and the well-known solution of the one-mode problem. The dependence of the amplitude and shape of the pulses on the amount of absorber is determined.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 15, No. 2, pp. 221–226, February, 1972.
