Question: Eric Mazur left Europe to pursue a postdoctoral study with which Nobel laureate recognized for his work i ndeveloping driving principles behind nonlinear optics for laser spectroscopy?

<P0-S0> Nicolaas "Nico" Bloembergen (March 11, 1920 – September 5, 2017) was a Dutch-American physicist and Nobel laureate, recognized for his work in developing driving principles behind nonlinear optics for laser spectroscopy. <P0-S1>  During his career, he was a professor at both Harvard University and later at the University of Arizona. <SEP> <P1-S0> Yuen-Ron Shen (沈元壤) is a professor emeritus of physics at the University of California, Berkeley, known for his work on non-linear optics. <P1-S1>  He was born in Shanghai and graduated from National Taiwan University. <P1-S2>  He received his Ph.D. in Applied Physics from Harvard under physicist and Nobel Laureate Nicolaas Bloembergen in 1963, and joined the department of physics at Berkeley in 1964. <P1-S3>  In the early years, Dr. Shen was probably best known for his work on self-focusing and filament propagation of laser beams in materials. <P1-S4>  These fundamental studies enabled the creation of ultrafast supercontinuum light sources. <P1-S5>  In the 1970s and 1980s, he collaborated with Yuan T. Lee on the study of multiphoton dissociation of molecular clusters. <P1-S6>  The molecular-beam photofragmentation translational spectroscopy that they developed has clarified much of the initial confusion concerning the dynamics of infrared multiphoton dissociation processes. <P1-S7>  In the 1980s and 1990s, Professor Shen developed various nonlinear optics methods for the study of material surfaces and interfaces. <P1-S8>  Among these techniques, second-harmonic generation and sum frequency generation spectroscopy are best known and now widely used by scientists from various fields. <P1-S9>  He has collaborated with Gabor Somorjai on the use of the technique of Sum Frequency Generation Spectroscopy to study catalyst surfaces. <P1-S10>  He is the author of the book "The Principles of Nonlinear Optics". <P1-S11>  Professor Shen belongs to the prolific J. J. Thomson academic lineage tree. <P1-S12>  Currently, Professor Shen works in U. C. Berkeley and Fudan University in Shanghai. <SEP> <P2-S0> Mazur studied physics and astronomy at Leiden University. <P2-S1>  He passed his "doctoraal examen" (equivalent to a master's degree) in 1977 and continued his graduate studies at the same institution. <P2-S2>  In 1981 he obtained his Ph.D on a thesis entitled "The structure of non-equilibrium angular momentum polarizations in polyatomic gases". <P2-S3>  Although he intended to go on to a career in industry with Philips N.V. in Eindhoven, he left Europe at the urging of his father, Peter Mazur, to pursue a postdoctoral study with recent Nobel laureate Nicolaas Bloembergen at Harvard University. <SEP> <P3-S0> Chen Yung-Jui received his BS in Physics from National Tsing Hua University in 1969 and Ph.D. in Physics at the University of Pennsylvania (1976). <P3-S1>  After a brief postdoctoral period at Penn, he joined the Advanced Microelectronic Laboratory at McDonnell Douglas Astronautics Co. in 1977. <P3-S2>  From 1980 to 1987, Dr. Chen conducted fiber optical communications related research at GTE Laboratories. <P3-S3>  During the ten years in industry, he worked on MOS/MNOS VLSI technology, wafer scale integration, Ultra-fast optical spectroscopy, nonlinear optics of semiconductors and organic polymers, integrated optics and optoelectronic devices. <P3-S4>  In 1987, he moved to academe and became one of the founding faculty members of the Department of Electrical Engineering at University of Maryland, Baltimore County.
