US Patent 7466734 Compact external cavity mid-IR optical lasers

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.
