Abstract

We describe the design and experimental result of a LD pumped Nd:YAG laser with 12J energy at repetition rate of 10Hz. The temperature distribution was controlled to less than 2℃ on the surface by means of uniform pump and cooling. The ASE was calculated by energy storage code and fit well with the measurement results which was about 1.72 in average. The beam quality was controlled by means of mechanical design and adjustment and compensation by a home-made deforming mirror. The far field was measured to 3.23 TDL. The stability of energy and pointing were paid great attention and control by means of full absorption and high stability mechanical design. The energy stability was less than1%(RMS) and pointing stability was 73μrad(PtV), which made the laser very comfortable for use.
