Abstract

Abstract: Photoacoustic pulses generated by pulsed laser irradiation have the characteristics of high frequency and wide bandwidth, which are desirable for imaging and sensing. Efficient photoacoustic composites have been developed for fabricating photoacoustic transmitters capable of generating high‐amplitude ultrasound. Here, recent advances in photoacoustic transmitters are reviewed from an application perspective, starting with the fundamental aspects of photoacoustic generation. The topics discussed include various composite materials for photoacoustic generation, and their applications such as high‐amplitude therapy, imaging and sensing, and photoacoustic waveform control. Abstract : Photoacoustic transmitters using pulsed laser irradiation onto optical nanomaterials have been developed for generating strong photoacoustic pulses, enabling interesting applications. Recent advances in photoacoustic transmitters are reviewed from an application perspective, starting with the fundamental aspects of photoacoustic generation.
