备注：: This manuscript is the previous version of our work. Now we have improved this work, and a new manuscript entitled "Short pulse close to round-trip time generated by cavity-less high gain Nd:GdVO4 bounce geometry"(ID:1904.04963 ) has been submitted to the arxiv. Therefore, we decide to replace the previous version

摘要：

我们演示了一个瓦级、kHz纳秒脉冲ASE源，其脉冲宽度接近其往返时间。ASE使用Nd：GdVO4高增益反弹几何结构，无需输出耦合器。采用电光调Q（EOQ）器件，在三种有效腔长下，获得了脉宽分别为2.28、1.73和1.17ns的高增益激光输出。所有这些脉冲宽度接近于相应的有效腔长的往返时间。在脉宽为1.17 ns时，获得了120 μ J的最大输出能量和100 kW的峰值功率。与腔倒空法相比，本研究提供了一种获得高峰值功率短脉冲的简便方法。

英文摘要：

We demonstrate a watt-level, kHz nanosecond-pulse ASE source with its pulse-width being close to its round-trip time. The ASE uses a Nd:GdVO4 high gain bounce geometry structure without an output coupler. Using an EOQ (electro-optics Q-switch) device with high extinction-ratio, the pulse-width reaches 2.28, 1.73 and 1.17 ns under three effective cavity lengths, respectively. All these pulse-widths are close to the round-trip time of the corresponding effective cavity lengths. With the pulse-width being 1.17 ns, maximum output energy of 120 μJ and peak power of 100 kW are achieved. This study offers a convenient method to obtain high-peak-power short pulses, comparing with cavity-dumping method.
