阐明了影响固体激光器输出功率的根本原因是自聚焦效应,而菲涅耳衍射产生的空间高频调制是加速自聚焦过程的重要因素.为了消除硬边光阑产生菲涅耳衍射,作者建议采用宽频带激光,并用实验演示了其消衍射效果.

高等学校实验教学承担着培养学生实践能力、创新能力和综合素质的重要任务。传统的实验教学模式在实验内容设置和安排上缺乏对学生自主研究、深度参与及提高综合能力的考虑,因而不利于学生个性和创新精神的养成。以《光电仪器电子学实验》课程为例提出了线上线下双反馈一体化的混合式实验教学模式。通过线上线下双反馈一体化的实验教学模式,可以形成一个发现问题、及时反馈、调整实验教学方案、跟踪评价并持续改进的闭环教育过程,有效提高学生学习的自主性、积极性,提高学习效果。
