Abstract
Highly compact quantum well based laser systems with external cavity configurations are tightly integrated in a very small mounting system having high thermal and vibrational stability. The mounting systems may include adjustability and alignment features specifically designed to account for the particular nature of the micro components used. The laser systems may provide for wavelength selection, including dynamic wavelength selection. The laser systems may also provide special output couplers.
Claims47
A laser comprising:
- a gain medium;
- and
- an optical resonator cavity,
- wherein the gain medium comprises a unipolar quantum well stack semiconductor structure, and
- wherein the optical resonator cavity is not more than about 30 millimeters in length and comprises at least two feedback elements arranged to couple a feedback beam to the gain medium, and at least one of said feedback elements is spatially removed from said gain medium.
