Kilowatt high power diode laser is reported with the ways of multi-wavelength and polarization coupling. The fast and slow axis beam parameter product is symmetrized by the method of shaping with the beam quality better than 12 mm·mrad and all-solid-state laser. 87.5% optical-optical efficiency of the high power diode laser is obtained. Through intelligent control, the diode laser can be outputted with different wave lengths, powers and pulse widths.
