The Birth of Nonlinear Optics---talk by professor Nicolaas Bloembergen

Although Professor Bloembergen used the old-fashioned projector, he delivered a wonderful talk on the early history of the nonlinear optics.

He started by saying that Ruby laser is nonlinear optics. Therefore, we should celebrate the birth of nonlinear optics 1 year earlier, together with the laserfest.


Applause continued for a long time after his talk.
