Miniaturization　and　integration　of　lasers　have　been　a　hot　topic　in　recent　years.　Colloidal　quantum　dots　(CQDS)　can　be　used　as　laser　gain　media　because　of　their　high　luminous　efficiency　and　low　threshold.　Compact　distributed　Bragg　reflector　(DBR)　combined　with　CQDs　is　used　to　construct　micro　laser.　In　this　paper,　CdTeSe/ZnS　core-shell　CQDs　were　prepared　by　aqueous　synthesis.　DBR　was　fabricated　by　magnetron　sputtering　using　SiO2　and　TiO2　through　reasonable　design　of　their　thickness　and　repetition　cycle　number.　CQDs　were　dropped　on　the　surface　of　DBR　to　form　a　low-cost　small-scale　surface　particle　laser　(SPL).　The　output　emission　of　770　nm　and　824　nm　dual　wavelength　laser　is　realized.　The　threshold　is　11　mW/cm2　and　the　bandwidth　is　1　nm.　The　micro　integrated　laser　with　high　intensity　and　Narrow　bandwidth　near　infrared　emission　has　been　completed.
