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.
