Coherent population transfer with Coherent population transfer with chirped few-cycle laser pulses in an excited-doublet four-level system

The efficient excitation to particular states has attracted much attention in both physics and chemistry[1-10]. The stimulated Raman adiabatic passage technique for pop- ulation transfer has been implemented with continuous or narrow band laser pulse (nanosecond time scale)[1], but the requirement for large pulse areas seems to advise against the use of short pulse lasers. However, the use of ultrashort laser pulse may have some distinct advan- tages, such as producing high energy frequencies,…     

大学物理实验课程问卷调查及改革实践

为提高大学物理实验教学质量,实验中心对大学物理实验课程进行了问卷调查,分析和总结了实验预习、教学指导、操作、报告等实验教学环节出现的问题.以问卷调查结果为课程改革依据,提出了将信息技术深度融合实验教学的改革方案.建设微信公众教学平台和虚拟仿真教学平台,辅助实验预习;建立以学生合作学习模式为主,教师指导为辅的教学指导模式...     

大学物理实验实例的思政挖掘

高等院校的课程思政教学体系需科学、合理设计,专业教育同思政教育要做到充分融合。大学物理实验既是理工科的一门公共基础课程,同时又是理科专业教育课程的基础课程,蕴含着丰富的思想价值和精神内涵。本文从三个大学物理实验实例出发,深入挖掘思政元素,具体分析、阐述实验如何帮助大学生形成正确的价值观,实验如何培养科学精神以及对科学思维方法的训练。激发课程育人功效,提高人才培养质量。
