| Abstract: | The paper focus on the characteristic of LD pulse-pumped Nd∶YVO4 laser.The laser performance was tested and compared with same duty cycle and different pulse width.Then we analyzed and compared the conversation efficiency under the same peak power.From the theoretical analysis of the impact of the cooling crystal,we got the conclusion that the crystal cooling efficiency and the accumulation of heat is in direct proportion.Though the analysis and comparison about the experiment's curves,we summed the impact on the output performance of the LD pulse-pumped Nd∶YVO4 laser.Then we got the way to improve the efficiency of pulse-pumped laser. |
