Abstract:
1. A laser system comprising: a first laser source that generates a first tunable optical signal that is tuned over a first spectral scan band, the first laser source having a first laser cavity defined by a first reflector and a shared reflector, the first laser source including a first gain element for amplifying light in the first laser cavity, a first tuning element for dictating a wavelength of the first optical signal, and a first lens for coupling light between the first gain element and the first tuning element; a second laser source that generates a second tunable optical signal that is tuned over a second spectral scan band, the second laser source having a second laser cavity defined by a second reflector and the shared reflector, the second laser source including a second gain element for amplifying light in the second laser cavity, a second tuning element for dictating a wavelength of the second optical signal, and a second lens for coupling light between the second gain element and the second tuning element; and an intracavity combiner located between the shared reflector and each of the first reflector and the second reflector for coupling light to the shared reflector and back into the first laser cavity and the second laser cavity.
