Description

A theory of generation of optoacoustic pulses of first and second sound in superfluid helium by the rectangular pulse of laser radiation generated by thermal mechanism was considered. It was found that all of the exciting pulses are formed in competition pulses generated at turning on and off the beam and have opposite phases. Numerical results showed that all generated optoacoustic pulses have bipolar shape.
