We report the development of an optically transparent high-frequency ultrasonic transducer using lithium niobate single-crystal and indium–tin–oxide electrodes with up to 90% optical transmission in the visible-to-near-infrared spectrum. The center frequency of the transducer was at 36.9 MHz with 33.9%, at −6 dB fractional bandwidth. The photoacoustic imaging capability of the fabricated transducer was also demonstrated by successfully imaging a resolution target and mouse-ear vasculatures in vivo , which were irradiated by a 532 nm pulse laser transmitted through the transducer.
