【摘要】 介绍了半导体激光器泵浦固体激光器的原理、Nd³⁺:YVO₄晶体和KTP晶体的性能,采用LD端面泵浦、直腔结构及腔内倍频方式实现了用半导体激光器作为泵浦源泵浦Nd³⁺:YVO₄晶体所产生的红外激光经KTP晶体后所产生的532nm绿光的整套实验装置。在此实验装置上完成了多项实验,并对记录的实验数据进行了分析处理,实验结果与理论结果相符合。所涉及的实验项目有:激光输出功率随驱动电流、LD制冷温度、谐振腔腔长的变化关系;倍频效率和光斑模式的调节等。更多还原

【Abstract】 The principle of laser diode-pumped solid-state laser,the performance of Nd³⁺:YVO₄ crystal and KTP crystal,and a experimental package of a pump source pump Nd³⁺:YVO₄ crystal,and the red light which produces after Nd³⁺:YVO₄ crystal into green light with 532nm with LD end-pumped,straight cavity and intracavity frequency doubled are introduced.In this experimental setup a number of experiments are completed,the experimental data are processed, experimental results with theoretical results are consistent.Involved in the projects are:the changes of the laser output power with drive current,temperature refrigeration of LD and resonator cavity length,efficiency of frequency-doubling, and the regulation of spot model.更多还原
