PHOTOTHERMOACOUSTIC TRANSFORMATION OF A KUMMER–GAUSSIAN LIGHT BEAM IN SEMICONDUCTOR SENSOR STRUCTURES ON THE BASIS OF CdTe
Abstract
We theoretically and experimentally investigated the process of laser photothermoacoustic transformation in sensor semiconductor structures. We obtained the expression for a pressure pulse describing the evolution of an ultrasonic response excited by a nanosecond laser pulse with a Kummer-Gaussian intensity distribution. The possibility of effective control of the process of photothermoacoustic transformation of laser pulses in semiconductor structures used for creating highly sensitive detectors of ionizing radiation was experimentally demonstrated.
