The radiation of pressure waves by a bubble layer near the free surface of a liquid excited by a high-intensity sound pulse has been studied. It was shown that the bubble layer exhibits the properties of a resonator with one partially transparent boundary. Bubbles on the boundary of the layer due to the interaction through the self-consistent field with the bubbles inside the layer perform collective pulsations. It was found that the emission spectrum of the layer is ruled. The lines of the emission spectrum of a layer have a regular composition and lie above the frequency of the intrinsic pulsations of bubbles.
