Abstract: A method and system are presented directed to a light valve projector with a laser-phosphor light converter. The phosphor converter converts excitation light in order to provide light to a light valve projector. The phosphor converter reduces the étendue of laser-phosphor light sources using a light pipe integrator system. The light pipe integrator system includes a light pipe integrator configured to mix the excitation light and reduce the spot size of excitation light entering the system from, e.g., a laser array. The excitation light is imaged onto a phosphor as it exits the light pipe integrator. The phosphor emits fluorescent light, in response to being illuminated by the excitation light, that enters the light pipe integrator. The light pipe integrator reduces the emission angles of the fluorescent light while maintaining the étendue of the fluorescent light. The system and method may include a reflective polarizer to polarize the fluorescent light.
