Prof. Daniel Gauthier was the General Co-Chair of the recent topical meeting of the Optical Society of America, Nonlinear Optics 2011 (NLO 2011), following his term at conference Program Co-Chair in 2009. The conference is usually held every two years on one of the islands of Hawai'i, where the 2011 meeting was the 10th time that it was held here. The location is ideal for fostering interactions, especially between scientists from the United States and the Pacific Rim countries. One highlight of the meeting was a special Symposium celebrating the 50th anniversary of nonlinear optics. In particular, the first observation of a nonlinear optical effect - second harmonic generation of a laser beam passing through a quartz crystal - was reported by Peter Franken and colleagues in Physical Review Letters in 1961. The Symposium brought together luminaries of the field of nonlinear optics, many of whom were deeply influenced by the Franken paper and who contributed substantially to the rapid development of this field. The Symposium speakers shared personal anecdotes of their early research in nonlinear optics as well as describing some of their recent work and vision for the future of the field. The conference remains very active with a record number of contributed submissions this year and a program including over 170 plenary, invited, and contributed presentations over five days. The conference banquet is a traditional Luau, where Prof. Gauthier enjoyed some time with his better halfand the conference participants. Prof. Gauthier also enjoyed some vacation time before and after the conference, including taking hikes in the mountains of Kaua'i and snorkeling with sea turtles.
