Abstract

We have investigated a multipass Yb : KGW disk amplifier based on the White cell configuration and pumped by a laser diode with a fibre output. It is shown that the three-mirror layout of the cell is three times more efficient than the four-mirror one, since the size and position of the signal beam on the surface of the active element do not depend on the cell number of passes. For a three-mirror cell scheme, a small-signal gain G = 168 is obtained in experiments for a pump power of 360 W. The experimentally achieved gain of two such amplifiers arranged in series is 6 × 104, which exceeds G 2 approximately two-fold.

多路Yb: KGW磁盘放大器

我们研究了一种基于白细胞结构的多通Yb: KGW圆盘放大器，该放大器由具有光纤输出的激光二极管泵浦。结果表明，由于信号波束在有源元件表面的大小和位置不依赖于通过的单元数，三镜单元布局的效率是四镜单元布局的三倍。对于三镜电池方案，在泵浦功率为360 W的情况下，实验获得了小信号增益G = 168。实验结果表明，串联两个放大器的增益为6 × 104，约为g2的两倍。
