A multi-wavelength switchable laser system configured at known wavelengths without the need for wavelength feedback/locking control. The system includes an optical gain element, e.g. a pump source; a laser cavity defined by electrically activated Bragg gratings, each having a prescribed operational wavelength; a control module for controlling actuation of the gratings to activate a selected one of the gratings for operation at a selected operational wavelength; and an appropriate lens for removing an output signal at the selected operational wavelength from the laser cavity to a fiber.
