Abstract: The imaging system includes a light source having a laser cavity. A light signal resonates in the laser cavity along an optical path that includes a tunable electro-optic configured to select wavelengths in multiple different wavelength bands. Electronics tune the electro-optic such the selection of wavelengths in the wavelength bands change in response to the tuning. The optical path includes a second optical component configured to select wavelengths in multiple different second wavelength bands. The output of the laser cavity has wavelengths that are common to one of the wavelength bands and one of the second wavelength bands.
