摘要：

For　high　power　diode　laser,　the　multi-wavelength　combining　is　an　effective　technology　of　improving　the　beam　brightness.　Based　on　the　combing　technology,　the　diode　laser　bar　is　described,　with　the　different　sample　grating　in　every　emitter　ridge,　which　can　have　stability　of　the　wavelength　and　the　single　longitudinal　mode.　Mathematics　computing　model　based　on　the　spilt-step　fourier　(SSF)　method　combining　is　built　using　MatLab.　It　simulated　the　multi-wavelength　combining　process　of　emitters.　In　simulation,　the　diode　laser　beam　successively　go　through　a　focus　lens　and　a　diffraction　grating,　respectively.　In　result,　the　model　accords　with　the　law　of　the　combining　which　is　verified　by　existing　report.　The　simulation　solution　satisfied　the　reported　experiment.　©　2018　The　Authors,　published　by　EDP　Sciences.
