We　investigate　the　random　lasing　properties　of　polycrystalline　MAPbBr　3　grown　in　a　hollow　fiber.　Coupling　of　the　random　lasing　on　the　inner　wall　of　the　hollow　fiber　into　the　annular　cylinder　and　guided　by　the　inner　surface　of　hollow　cavity　enable　directional　output　of　the　random　lasing　emission.　The　polycrystalline　MAPbBr　3　was　grown　by　the　capillary　effect,　when　one　end　of　the　hollow　fiber　was　dipped　into　the　precursor　solution.　A　two-photon　pumping　scheme　was　employed,　where　femtosecond　pulses　centered　at　about　800　nm　was　focused　onto　the　MAPbBr　3　polycrystals　through　the　side　wall　of　the　hollow　fiber.　Random　lasing　was　achieved　due　to　the　strong　optical　scattering　by　the　interfaces　within　the　polycrystals　on　the　inner　wall　of　the　hollow　fiber.　The　random　lasing　output　was　re-collimated　into　a　roughly　parallel　beam　with　a　circular　transverse　mode,　which　favors　farfield　applications　of　random　lasers.　Two-photon　pumping　enables　larger　penetration　depth　and　larger　excitation　volume　than　single-photon　pumping,　so　that　strong　lasing　spot　can　also　be　observed　in　the　center　area　of　the　output　laser　beam.
