中文摘要：

如何有效地减少抽运过程和激光发射过程中激光介质内产生的热量，是全固态高功率激光研究过程中所面临的主要难题之一。与传统波长的抽运方式相比，采用长波长的直接抽运技术不但可使激光介质中产生的热量减少30％～50％，而且还可显著改善激光的输出特性。以最常用的Nd^3＋激光器的研究作为切入点，简述了直接抽运技术的研究发展，介绍了直接抽运技术相对于传统抽运技术的优缺点以及目前的研究现状，最后对未来的发展前景作了初步分析和展望。

英文摘要：

It is one of the most important questions to reduce the thermal effect and accumulation in the laser medium effectively, by pumping and lasing in the research of laser diode pump solid-state laser （DPSSL） at high power laser level. Compared with the conventional pumping scheme, direct pumping scheme at longer wavelength will not only reduce the heat by 30 % -50 %, but also improve the laser performances significantly. The development and status of direct pumping DPSSL based on the research of the Nd^3＋ doping laser are reviewed, the characteristics of the new pumping scheme and the progresses on Nd doping lasers are introduced. Finally, the new development in the future is prospected.
