Mobile projectors require high efficiency light sources. Our green laser achieves high efficiency in a compact form with excellent beam quality and high bandwidth. The infra-red output of a distributed Bragg reflector laser is coupled into a second harmonic generation device and converted to green. Efficiencies of 15% are achievable.
