    “…Here, we utilize a laser ultrasound sensor to develop a miniaturized, optical-resolution photoacoustic endoscope. The sensor can boost the acoustic response by a gain factor of ω(o)/Ω (the frequency ratio of the signal light and measured ultrasound) by measuring the acoustically induced optical phase change. …”
