Abstract
Systems and methods for adjusting optical path length of an optical path are provided. The systems and methods can be used to controllably adjust optical path length in an external cavity laser. A representative optical path having a first end and a second end comprises a first transparent refractive element located in the optical path between the first end and the second end. The transparent refractive element is adjustable to adjust the optical path length of the optical path without changing the physical distance between the first end and the second end. A representative method includes introducing a transparent refractive element into the optical path and adjusting the transparent refractive element to change the optical path length without changing the physical distance between the first end and the second end of the optical path.
