A laser-emitting device may be coupled to an electro-optically controlled wavelength actuator. An electro-optically controlled wavelength actuator may be a holographic wavelength actuator or a liquid crystal wavelength actuator. The electro-optically controlled wavelength actuator may function as a tunable diffraction grating for external cavity lasers.
