Resonator Based External Cavity Laser

摘要

An external cavity laser comprises a gain medium and an external cavity resonator without the use of a semi-reflective surface placed between the gain medium and the resonator. Radiation from the gain medium is reflected back to the gain medium by one or more resonant backscattering regions of the resonator, such that the entire optical path between the gain medium and the external cavity resonator could be free from a reflective surface.

主权项

1. An external cavity laser, comprising:
a gain medium that emits electromagnetic radiation; a TIR resonator having a resonant backscattering region that reflects at least a portion of the radiation from the gain medium back to the gain medium; and an optical pathway between the gain medium and the resonator, wherein the optical pathway is free from a reflective surface, wherein the radiation from the gain medium travels to the resonator via the optical pathway, and wherein backscattered radiation from the resonator travels to the gain medium via the optical pathway.
