A new principle of mode locking is analyzed: additive pulse mode locking. It is shown to be operative in two-cavity soliton lasers, but it also permits mode locking with fibers in the positive dispersion regime. A simple model is developed that displays the pulse-shortening mechanism. Parameter ranges, within which this principle can be exploited, are given. Comparisons with experiments are made.
