 报告一(主要面向我校教师和博硕研究生)

报告时间:717日(周一)上午9:30

报告地点:科学园1D412会议室(超精密光电仪器工程研究所)

报告题目:Recent Research Activities on Ultrafast Optics and Photonics at KAIST

报告摘要:Precision is a common aspect that governs most of strategically important technologies for IT, BT, NT and aerospace industry. In response to ever-growing demands on precision, various laser sources have been used to attain sub-wavelength precision in many fields of fabrication and measurements by means of photons. The precision-directed laser photonics will continue to advance to the direction of ultra-precision to achieve better resolutions, larger functional ranges, higher throughputs, and more improved stability. Nonetheless, light sources available today are limited in the wavelength bandwidth, photon energy, spatial and temporal coherence, and peak power, which consequently hinders breakthroughs toward the realm of ultra-precision. The main objective of research activities at KAIST is to investigate the technological possibilities of femtosecond lasers with the aim of establishing the new foundation for ultra-precision that will enable nanometer scale metrology and fabrication over extensive ranges as demanded in the next generation of precision engineering. To the end, a systematic approach will be pursued to generate noble coherent light sources covering the whole optical spectrum spanning from THz waves to X-ray radiation by making the most of ultrafast femtosecond laser pulses.

 报告二(主要面向我校本科生)

报告时间:718日(周二)下午19:00

报告地点:二校区主楼B22教室

报告题目:Precision Engineering Metrology: Technology Trends

报告摘要:Metrology is the science of measurement, embracing both experimental and theoretical determinations of physical quantities at any level of uncertainty needed for versatile technological developments. This lecture begins with two fundamental physical quantities, time and length, by explaining how they are physically defined and practically measured to the utmost precision achievable today. As the importance of photonics grows in measurement of diverse physical quantities, basics of optics especially for electromagnet wave interference are addressed with laser interferometry. And, traditional systematic engineering measurement practices based on electromagnetic and quantum physics are treated with their applications for industrial precision measurements.
