The　color　and/or　chromaticity　controllability　of　random　lasing　is　a　key　factor　to　promote　practical　applications　of　random　lasers　as　high　luminance　sources　for　speckle-free　imaging.　Here,　white　coherent　random　lasing　with　tunable　chromaticity　is　obtained　by　using　broadband　enhancement　Au-Ag　nanowires　as　scatterers　and　the　resonance　energy　transfer　process　between　different　dyes　in　the　capillary　microfluidic　channel.　Red,　green　and　blue　random　lasers　are　separately　fabricated　with　low　thresholds,　benefiting　from　the　plasmonic　resonance　of　the　nanogaps　and/or　nanotips　with　random　distribution　and　sizes　within　Au-Ag　nanowires　and　positive　optical　feedback　provided　by　the　capillary　wall.　A　white　random　laser　system　is　then　designed　through　reorganizing　the　three　random　lasers.　And,　the　chromaticity　of　the　white　random　laser　is　flexibly　tunable　by　adjusting　pump　power　density.　In　addition,　the　white　random　laser　has　anisotropic　spectra　due　to　the　coupling　role　between　the　lasers.　This　characteristic　is　then　utilized　to　obtain　different　random　lasing　with　different　chromaticity　over　a　broad　visible　range.　The　results　may　provide　a　basis　for　applying　random　laser　in　the　field　of　high　brightness　illumination,　biomedical　imaging,　and　sensors.　(C)　2020　Optical　Society　of　America　under　the　terms　of　the　OSA　Open　Access　Publishing　Agreement
