Power control consists of forward link (downlink) power control and backward link (uplink) power control.
功率控制分前向链路（下行链路）、反向链路（上行链路）功率控制。

Under continuous wave pumping, backward amplified spontaneous emission output power (ASE-) rapidly increases to peak value, and then decreases monotonically to steady-state value.
在连续波泵浦下，反向自发辐射输出功率（ASE-）首先快速地增加到峰值功率，然后单调下降到稳态值；

In this paper, high efficient backward stimulated Raman compression is obtained pumped by high power KrF laser using focused beam geometry.
