Laser Diode pumped all-solid-state laser has been one of key research branches in the solid-state laser field recently. In this thesis, Based on the advantages of diode-pumped solid-state laser(DPSSL) in Chapter 1, the development of diode-pumped solid-state laser is introduced. The trends of DPSSL are pointed out, the wide application fields ,as well as the bright market future of high power DPSSL are also summarized. In the Chapter 2 , all kinds of solid-state laser gain materials are introduced in detail. In the Chapter 3 , the theory on the mode-matching of the pump beam and the cavity mode is analyzed in detail based on the basic theory and work principle of LD-pumped all-solid-state laser. In the Chapter 4 , a two rod series connection Nd:YVO4 all-solid-state laser with a flat-flat cavity two-end-pumped by a fiber- coupled LD was reported for the first time to our knowledge in this paper at home. 11 W of CW 1.06m TEM00 mode output has been obtained at a 23.05W pumping power with an optical-optical conversion efficiency of 47.72%. Also the results at different concentration and at the same time the experimental results were discussed.
