Abstract: A high intensity solid state light pulse generator, has a low voltage, low range radio frequency carrier wave generator, the output of which is modulated by a low frequency sweep signal, to generate sonoluminescent light pulses visible to the human eye, within a desired spectrum. The modulating sweep signal can be computer generated in a predetermined mode, for a range of outputs. In one embodiment, a carrier wave at 450 kHz is modulated by way of an input in the audio range of 20 to 20,000 Hz. The colour of the output pulses is held to be a function of the modulating frequency. By selection of a suitable modulating frequency, monochromatic light pulses of a predetermined colour may be provided. A semi-mirror laser technique is used in order to amplify the light pulses, to achieve high intensity bursts of light at reduced frequency.
