Abstract
In some embodiments, an apparatus includes a first laser cavity including a set of high-reflector gratings coupled in series and a second laser cavity including a set of high-reflector gratings coupled in series. Each high-reflector grating has an associated spectral bandwidth. The first laser cavity is configured to receive at a first end optical energy having a first spectral bandwidth and the second laser cavity is configured to receive at a first end optical energy having a second spectral bandwidth. A fiber coupler is coupled to a second end of the first laser cavity and to a second end of the second laser cavity. The fiber coupler is configured to receive optical energy from the first laser cavity having a third spectral bandwidth greater than the first spectral bandwidth, and receive optical energy from the second laser cavity having a fourth spectral bandwidth greater than the second spectral bandwidth.
