Abstract
External cavity diode laser (ECDL) devices and methods for producing the same are described that allows ECDLs to be readily produced and configured to operate at a desired range of wavelengths, while allowing tunability of the output wavelength. One ECDL includes a laser gain chip including a gain medium, a first reflective surface at a first end of the gain medium, and a second surface at a second end of the gain medium opposite to the first reflective surface. The second surface has a facet that forms an angle approximately equal to Brewster's angle for light having a first wavelength. The ECDL further includes a diffraction grating positioned to receive light that passes through the second surface, to operate as a mirror in the external cavity diode laser, and to allow a portion of the light to be directed outside of the external cavity diode laser as output light.
