Abstract: A laser device includes a laser (600) and a controller (622). The laser has an optical cavity (602) that includes an active gain section (604) and a phase shifter (606). The controller is configured to excite the active gain section to lase light out of the optical cavity. The controller is further configured to, while the light is being lased out of the optical cavity, modulate a refractive index of the phase shifter to shift an optical phase of lasing modes of the lased light to thereby reduce coherence of the lased light.
