Abstract
Mode-hopping is a typical, but undesirable feature of many lasers, being particularly noticeable and troublesome in lasers designed for single-frequency operation. It occurs as the result of small changes in cavity length, or shift (eg. due to temperature change ) of the gain peak, Elimination of mode hopping can add considerable complexity to a laser, as typical counter measures include active stabilization of the resonator length to a stable reference cavity, and temperature stabilisation of the gain medium.
