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。
A high energy pulsed terahertz (THz) laser is studied experimentally. The laser cavity simply consists of a quartz glass waveguide, a coated GaAs input window, and a crystal quartz output window. NH
Biophotonics is an exciting and fast-expanding frontier which involves the fusion of advanced photonics and biology. It has not only created many novel methodologies for biomedical research, but also achieved many significant results as an independent fie
A diode-pumped Nd:YAG oscillator laser with an end-pumped zigzag slab architecture and weak pump absorption is developed. An output power of 253 W with a slope efficiency of 50.2% and an optical-optical conversion efficiency of 39.6% is achieved from the
