Coherence properties are what distinguish a laser from other source of light and what make a laser useful. We have demonstrated a polariton laser with coherence reaching the intrinsic limit of single-mode matter-wave lasers for the first time. We have demonstrated intensity coherence at the shot-noise limit expected of an ideal coherent state and phase coherence revealing interactions within the polariton condensate due to its matter-wave nature. The work was published in Coherent Polariton Laser, Phys. Rev. X 6, 011026 2016, and was discussed in Focus Polariton Laser Upgrade, Physics 9, 27 2016 and Toward a Better Polariton Laser, Optics and Photonics News, March 2016.
