Abstract

Stable interferometrically insensitive operation of an additive- pulse mode-locked Nd:YLF laser is observed over 4.8 μm of continuous detuning of the cavity lengths. This phenomenon continuously persists over 250 μm of coarse cavity-length detuning. Outside this range interferometric mode locking typically associated with additive-pulse mode locking is observed for detuning lengths of over 1 mm. The external cavity of the system consists of a multimode fiber whose four possible second-order proper modes are all excited. The underlying mechanism is a slow process with response times in the subhertz and hertz regions.
