无反转光放大及无反转激光一直是激光物理学研究中的重要课题．实现短波长区域的无反转光放大尤其引人注目．其中，如何实现激光上能级的非相干泵浦是待解决的难点之一．本文提出一种不要非相干泵浦而实现无反转光放大的方案，希望它在短波长无反转激光的探讨中有所帮助． 论文
Non-inverted light amplification and non-inverted laser has been an important issue in laser physics research. The realization of non-inverted light amplification in the short wavelength region is particularly noticeable. Among them, how to realize incoherent pumping at the laser level is one of the difficulties to be solved. In this paper, we propose a non-inverting optical amplifier without incoherent pumping, and hope it can be helpful in the discussion of short wavelength non-inverting laser. paper
