High-power, fundamental transverse mode laser
This patent describes an optical source comprising: first and second reflectors separated from and opposite to each other for forming a single resonant optical cavity, a semiconductor gain medium having a major surface including a stripe contact extending longitudinally and transversely along the major surface for defining a large optical cavity in a volume of the gain medium thereunder, the semiconductor gain medium for generating a high-power optical signal by spontaneous emission, a single-mode optical fiber coupled to the semiconductor gain medium responsive to the high-power optical signal for causing a fundamental transverse mode optical signal to be amplified by the gain medium, the semiconductor gain medium and the single-mode optical fiber being disposed within the single resonant optical cavity formed by the reflectors, the optical source for producing stimulated coherent radiation in a fundamental transverse mode.
