Laser photothermoacoustic transformation in sensor semiconductor structures was experimentally and theoretically investigated. An expression for a pressure pulse describing the evolution of an ultrasonic response excited by a nanosecond laser pulse with a Kummer-Gaussian intensity distribution was obtained. The possibility of effective control of photothermoacoustic transformation of laser pulses in semiconductor structures used for creating highly sensitive detectors of ionizing radiation was experimentally demonstrated.
