Hybrid　lead　halide　perovskites　have　made　great　strides　in　next-generation　photovoltaic　and　optoelectronic　devices.　Random　lasers　based　on　perovskite　materials　have　been　intensively　investigated,　but　the　miniaturization　of　perovskite　random　lasers　has　not　been　achieved　up　to　now.　Here,　we　report　the　fabrication　of　perovskite　random　lasers　based　on　perovskite　films　deposited　on　the　optical　fiber　facets　using　a　dip-coating　method.　Under　optical　pumping　conditions,　random　lasing　was　observed　with　minimum　threshold　energy　of　32.3　mu　J/cm(2)　at　similar　to　550　nm;　also,　the　lasing　threshold　decreased　with　increasing　diameter　of　the　optical　fiber.　The　results　show　that　the　random　lasing　emission　originates　from　the　scattering　between　the　perovskite　crystal　grains,　and　the　decreased　threshold　is　attributed　to　the　increased　active　area　of　the　perovskite　film.　The　directionality　of　perovskite　random　lasers　indicates　that　the　divergence　angle　of　the　laser　beam　is　less　than　60　degrees.　We　also　demonstrate　that　the　perovskite　random　laser　on　the　fiber　facet　can　prevent　speckle　formation　and　improve　image　quality.　These　results　may　promote　the　applications　of　random　lasers　in　compact　sources　and　integrated　optoelectronic　devices.
