Abstract

Abstract. A four-rod/four-TEM00-mode beam off-axis parabolic mirror solar pumping concept is proposed. Four off-axis parabolic mirrors with 10 m2 total collection area were used as the primary solar concentrators to pump four 3.1-mm diameter, 84-mm length neodymium-doped yttrium aluminum garnet (Nd:YAG) rods within four 2V-shaped pump cavities through four secondary fused-silica aspheric concentrators and four rectangular fused-silica light guides, ensuring a good absorbed pump power distribution within each rod and avoiding the serious thermal lensing and thermal stress issues associated with classical single large rod solar lasers. The laser design parameters were optimized using ZEMAX© and LASer Cavity Analysis and Design (LASCAD©) analysis software to maximize the TEM00-mode laser power. 155.29-W TEM00-mode total laser power was numerically calculated, corresponding to 15.5 W / m2 solar laser collection efficiency and 1.72% solar-to-TEM00-mode laser conversion efficiency, respectively. This result represents an improvement of nearly 2 and 1.24 times, in solar laser collection efficiency and solar-to-TEM00-mode laser conversion efficiency, respectively, as compared with the previous experimental records of the TEM00-mode solar laser pumped through the parabolic mirror primary concentrator. It provides also a 1.14 and 1.19 times improvement, as compared to the previous numerical record of the TEM00-mode solar laser pumped by the Fresnel lens primary solar concentrator.

使用四个Nd:YAG棒/四个离轴抛物面反射镜抽运方法的高效tem00模式太阳能激光器

摘要提出了一种四杆/四tem00模式光束离轴抛物面镜太阳能泵浦概念。采用4个总收集面积为10 m2的离轴抛物面镜作为主聚光器，通过4个二次熔融硅非球面聚光器和4个矩形熔融硅光导，将4个直径3.1 mm、长度84 mm的掺钕钇铝石榴石(Nd:YAG)棒泵入4个2v形的泵腔内。确保每个棒内良好的吸收泵浦功率分布，避免与经典单棒太阳能激光器相关的严重热透镜和热应力问题。利用ZEMAX©和laser Cavity Analysis and design (LASCAD©)分析软件对激光器设计参数进行优化，使tem00模式激光功率最大化。数值计算了155.29-W tem00模式激光总功率，对应的太阳能激光收集效率为15.5 W / m2，太阳- tem00模式激光转换效率为1.72%。该结果表明，与以往通过抛物面镜主聚光器抽运tem00模式太阳激光的实验记录相比，太阳能激光的收集效率和太阳到tem00模式激光的转换效率分别提高了近2倍和1.24倍。它还提供了1.14倍和1.19倍的改进，与以前的数值记录相比，由菲涅耳透镜主太阳聚光器泵浦的tem00模式太阳激光。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
