Abstract
A theoretical and experimental study is conducted to investigate applicability of a single-mode fiber ultrasonic sensor for detecting the shock-wave in optical breakdown in air induced by a high power laser pulse. The sensor is based on the ultrasonically induced modal birefringence which alters the polarization state of the optical beam propagating through the fiber. The shock-wave signals have been gotten by using the sensor. It is shown that the single-mode fiber sensor has enough sensibility to detect shock-wave in air, but it is dependent on the fiber- ultrasonic interaction length and the intensity of shock- wave.
