The invention discloses a high-consistency photoacoustic excitation and detecting integrated fiber probe, a manufacturing method and a testing method thereof. According to the probe, a light absorbingmaterial (such as graphene or molybdenum disulfide and the like) and an elastic material (PDMS) are combined and deposited on the end surface of a double-clad fiber, and high-power pulse laser is utilized for performing photoacoustic signal excitation. Furthermore a light-absorbing sensitive material and a single-mode fiber end surface form a Fabry-Perot (F-P) interference chamber for realizing photoinduced ultrasonic signal detection. The probe has a photoacoustic excitation function and a detecting function and can be manufactured and formed in one time. Furthermore because the light absorbing material is prepared through a chemical liquid phase deposition method, the high-consistency photoacoustic excitation and detecting integrated fiber probe has advantages of controllable thickness,low number of steps, high repeatability, etc. Therefore, the fiber type photoactoustic probe has advantages of photoacoustic signal receiving-and-transmitting integration, small size, simple manufacture, high consistency, high photoacoustic conversion efficiency, high electromagnetic interference resistance, etc. The high-consistency photoacoustic excitation and detecting integrated fiber probe can be used in the fields such as industrial nondestructive detection, biomedical ultrasonic and material characteristic measurement.
