Dual-frequency vertical-external-cavity surface-emitting laser device for THz generation and method for generating THz

摘要

A laser device for generating an optical wave including at least two frequencies, such laser device including:a first element including a gain region, a second mirror, distinct from the first element, and arranged so as to form with a first mirror an optical cavity including the gain region;means for pumping the gain region so as to generate the optical wave;means for shaping the light intensity of the optical wave arranged for selecting at least two transverse modes of the optical wave; andmeans for shaping the longitudinal and/or transversal phase profile of the optical wave and arranged for adjusting at least two transverse modes of the optical wave.
