Nicolaas Bloembergen is Visiting Scientist at University of Arizona, Optical Sciences Center.

Nicolaas Bloembergen marries Huberta Deliana Brink in Amsterdam.

Nicolaas Bloembergen becomes Junior Fellow of Society of Fellows at Harvard University. He studies microwave spectroscopy and some nuclear physics at the Harvard cyclotron.

Nicolaas Bloembergen begins his Ph.D. at Harvard six weeks after Purcell, Torrey and Pound have detected nuclear magnetic resonance (NMR) in condensed matter. Since they are busy writing volumes for the M.I.T. Radiation Laboratory series on microwave techniques, he is hired as a graduate assistant to develop a first NMR machine. The results are laid down in one of the most-cited physics papers, commonly referred to as BPP (N. Bloembergen, E.M. Purcell and R.V. Pound , Phys. Rev. 73, 679, 1948).

Bloembergen enters University of Utrecht. Professor L.S. Ornstein allows him and J.C. Kluyver to skip some laboratory’s routines and instead assist G.A. W. Rutgers, a graduate student, in a Ph.D. research.

Nicolaas Bloembergen joins University of Arizona, Optical Sciences Center/College of Optical Sciences as Professor. He continues his research in nonlinear optics with special emphasis on interactions of picosecond and femtosecond laser pulses with condensed matter and of collision-induced optical coherences.

Nicolaas Bloembergen becomes Gordon McKay Professor of Applied Physics at Harvard University.

Nicolaas Bloembergen becomes Rumford Professor of Physics at Harvard University.

Nicolaas Bloembergen becomes Associate Professor at Harvard University.

Nicolaas Bloembergen hides from the Nazis with his family, eating tulip bulbs and reading Kramers' book Quantum Theorie des Elektrons und der Strahlung.

Nicolaas Bloembergen attends the Municipal Gymnasium in Utrecht. He decides to study physics probably because that is the most difficult and challenging subject he has encountered. He loves outdoor activities including competitive field hockey.

Bloembergen's group studies nuclear quadrupole interactions in alloys and imperfect ionic crystals, discovers the anisotropy of the Knight shift in noncubic metals, the scalar and tensor indirect nuclear spin-spin coupling in metals and insulators, the existence of different temperatures of the Zeeman, exchange and dipolar energies in ferromagnetic relaxation, and a variety of cross relaxation phenomena. All this activity culminated in the proposal for a three-level solid state maser in 1956.

Nicolaas Bloembergen works as Gerhard Gade University Professor at Harvard University. In 1990 he becomes Professor Emeritus.

Nicolaas Bloembergen is born in Dordrecht, the Netherlands as second child of Auke Bloembergen, a chemical engineer and Sophia Maria Quint. He is raised in the protestant work ethic in which intellectual pursuits are very encouraged.

Nicolaas Bloembergen takes a course on statistical mechanics by L. Rosenfeld, he does experimental work on noise in photoelectric detectors, and he prepares the notes for a seminar on Brownian motion given by J.M.W. Milatz. Bloembergen obtains his M.Sc. degree just before the Nazis close the university in 1943.

In 1948 Nicolaas Bloembergen submits his Ph.D. dissertation, Nuclear Magnetic Relaxation, in Leiden where he passes qualifying criteria. He works on establishing the nuclear spin relaxation mechanism by conduction electrons in metals and by paramagnetic impurities in ionic crystals, the phenomenon of spin diffusion, and the large shifts induced by internal magnetic fields in paramagnetic crystals.

Nicolaas Bloembergen receives half of the Nobel Prize in Physics along with Arthur L. Schawlow "for their contribution to the development of laser spectroscopy".

Nicolaas Bloembergen publishes Nonlinear Optics, a classic work in which he outlines the group’s theoretical and experimental efforts to analyse how electromagnetic radiation interacts with matter. The application and control of nonlinear optical effects today have become an essential part of a variety of areas such as optical communication, biomedical optics, and chemical analysis.

Nicolaas Bloembergen is Visiting Scientist at University of Central Florida, CREOL, The College of Optics and Photonics.
