Efficient pump-probe sampling with a single-cavity dual-comb laser: Application in ultrafast photoacoustics

Dispersive coherent Brillouin scattering spectroscopy

“…However, as of the current proof-of-principle experimental setup, the acquisition speed does not surpass asynchronous optical sampling (ASOPS) systems [31] , [32] , [42] , [43] , [44] , [45] , which improved the acquisition rate to a few seconds per point. The frame interval of the image sensor used as a multichannel detector limits the overall measurement time for our current setup.…”

“…Consequently, the conventional scanning method of delay time limits the signal acquisition speed or increases the electronic complexity. In recent years, various technological advancements have been underway to solve the above issues, such as the development of laser sources including free-running dual comb laser oscillators [31] , [32] and the simplification of the adjustment method for the repetition offset of two mode-locked pulsed laser sources [33] .…”

Special issue introduction: Ultrafast photoacoustics

“…One uses a mechanical delay line to introduce a time delay between the pump and probe pulses, whereas the other uses two lasers with slightly different repetition frequencies for asynchronous stroboscopic detection. Article [24] examines the performance of a system in which the two pulse trains required for asynchronous detection are derived from a single laser by introducing a birefringent crystal into the laser cavity. This simplifies the setup, makes it more compact, and ensures excellent performance.…”
