“… The future always belongs to the younger generation. Since the field continues to attract bright students, it may be expected that unexpected new developments will occur. Generally, history is highly nonlinear, and the course of revolutions and the rise and fall of empires is difficult to predict. The future course of nonlinear optics is also unpredictable. …”
