The discovery of gravitational waves from binary black hole mergers hasrenewed interest in primordial black holes forming a part of the dark matterdensity of our Universe. Various tests have been proposed to test thishypothesis. One of the cleanest tests is the lensing of fast radio bursts. Inthis situation, the presence of a compact object near the line of sightproduces two images of the radio burst. If the images are sufficientlyseparated in time, this technique can constrain the presence of primordialblack holes. One can also try to detect the lensed image of the mini-burstswithin the main burst. We show that this technique can produce the leadingconstraints over a wide range in lens masses $\gtrsim$ 2 $M_\odot$ if theprimordial black holes follow a single mass distribution. Even if theprimordial black holes have an extended mass distribution, the constraints thatcan be derived from lensing of fast radio bursts will be the most constrainingover wide ranges of the parameter space. We show that this technique can probeexotic compact boson stars and fermion stars made up of beyond the StandardModel particles. This search strategy is competitive and can provide theleading constraints on parts of the particle physics parameter space whencompared with gravitational wave observations.
