Professor Walid Tawfik is the group leader in the field of laser spectroscopy and ultrafast lasers at the National Institute of Laser (NILES), at Cairo University and visiting professor at Georgia institute of technology, USA. In 1994 he joined NILES as staff member and promoted as assistant lecturer, assistant professor and associate Professor in 1996, 2000, and 2008, respectively. He received the B.SC, Master and Ph.D degrees in physics, laser physics, and laser spectroscopy in 1992, 1996, 2000, respectively, from Cairo University, Egypt. His interested in the field of ultrafast lasers and ultrafast phenomenon. He has built Fewcycle ultrafast system of 5-fs pulse duration and 0.6 mJ at 1 kHz and published 46 papers. He is a senior member of different international professional societies like IEEE, OSA, APS, and SPIE. He has been collaborated with different international groups in USA, Japan, South Korea Saudi Arabia and Germany.
Prof. Walid research plans are devoted to ultrafast optics and photonics: nonlinear interactions of short laser light and matter using time-resolved spectroscopy for laser-pulse durations from nanosecond to few-cycle. The ultrafast pulses are characterized using autocorrelator, SPIDER, and FROG measurements. The studies include the application of laser-induced breakdown spectroscopy (LIBS) used in the field of analytical spectroscopy and plasma characterization, in addition to ultrafast nonlinear phenomena due to propagation of ultrafast pulses in nonlinear medium and how the interactions can be exploited for improved material characterization.
