Abstract
An apparatus for super-resolution Brillouin microscopy includes a probe laser that emits a first laser beam and a first objective lens that focuses the first laser beam onto a sample. The apparatus further includes a pump laser that emits a second laser beam and a second quarter-wave plate that receives the second laser beam. The apparatus further includes a depletion laser that emits a third laser beam that passes through a phase plate to modify its wavefront phase such that the third laser beam has a donut shape, and a second objective lens that focuses the second laser beam and the third laser beam onto the sample. Characteristically, the beam spot from the depletion laser is overlaid with the Gaussian-shape beam spots of the first laser beam and the second laser beam at the same focal plane. A detector is configured to detect a stimulated Brillouin gain signal and a stimulated Brillouin loss signal.
