Abstract
The transformation of Gaussian beam into a flat top one is realized by interaction of laser beam with two perpendicular sinusoidal ultrasonic waves operating in Raman–Nath regime. In this paper we propose, theoretically demonstrate and numerically illustrate a convex-concave beam, having the same principle of flat top one, using a frequency-modulated ultrasonic wave. The novelty of this beam is that its intensity varies periodically and regularly as function of time. Furthermore, the amplitude and the frequency of this variation can be controlled, easily by acting on the frequency excursion and modulating signal frequency respectively. Finally, the change in intensity between the centre and the edges of beam will enable to find promising results in future.
