See the beautifulness behind the lights. An Ultraviolet laser at 400nm is produced and emitted from a piece of nonlinear crystal where Second Harmonic Generation halved the 800nm infrared laser’s wavelength, combining two photons into a new photon with its energy doubled. This process is one of the widely used techniques in laser optics that help scientists with making breakthroughs.
