RESUMEN
A diode-pumped nanosecond eight-pass amplifier with Nd:YVO4 crystal was developed. Combined with the advantages of direct pumped and Innoslab structure, a high energy pulse was obtained by using the wedged multi-folded configuration with two plane mirrors. The 0.4mJ Q-switched seed at the pulse repetition frequency of 10kHz was amplified to 8.4mJ with the pump power of 330W, and the corresponding optical-to-optical efficiency was 29.8%. The M2 factors in the horizontal direction and vertical direction were 1.48 and 1.39, respectively. And no remarkable of ASE was observed.
