Abstract
A laser source with an optical resonator includes a laser gain medium with a low reflective first facet emitting a laser beam within the optical resonator. A wavelength dependent mirror receives the laser beam and reflects back a wavelength separated laser beam. A beam splitter divides the wavelength separated laser beam into a feedback beam directed toward the laser gain medium and a first output beam to be coupled out of the optical resonator. As a first improvement, the laser gain medium includes a second facet which is partly reflective, so that the second facet emits a second output beam of the laser source. As a second improvement, the laser source further includes a mirror arranged in a way that a beam diffracted by the wavelength dependent mirror is reflected back and again diffracted by the wavelength dependent mirror, so that the twice diffracted beam provides the wavelength separated laser beam.
