A thermoacoustic system with double acoustic drivers was constructed, which was composed of double speakers, a resonator, regenerator distributed in resonator and heat exchanger.
In order to improve the output quality of the laser, we brought forward the concept of double pre-ionization, which is beneficial for the effective excitation of the laser media in the resonator.
