Paper Abstract

Laser generation of longitudinal ultrasonic waves in the quartz glass without of the sputtered absorbing metal layer is experimentally studied. For exaltation of ultrasound, the Q-switched solid-state laser having of laser-pulse duration 25 nanoseconds is used. Registration of ultrasound performed by non-contact broadband receiver – the laser interferometer that have of frequency range 0.5 – 80 MHz. Installation for precision measurements of ultrasonic waves velocity in solids on the basis of non-contact optical methods of excitation and reception of ultrasound is presented. Results of measurements of velocity of longitudinal ultrasonic waves in samples made of quartz glass with the thickness 1.5 – 100 mm are given. The expanded uncertainty of measurements makes 0.01 – 0.5 %.
