摘要：

It is shown that the amplification of a finite-bandwidth thermal light beam always leads to a severe degradation of the signal-to-noise ratio by means of additive noise. Such degradation renders light amplification essentially useless as a means of signal enhancement for imaging faint stellar objects.
