By propagating an infrared laser beam with a wavelength of 1030 nm through a BBO crystal (beta barium-borate) cut for second harmonic generation there is not only an observation of frequency doubling (i.e. green at 515 nm) but also a bluish glow at 480 nm when a phase mismatch is achieved. Welcome to the world of nonlinear optics!
Remark: The violet light on the left is a result of the infrared sensitivity of camera CCD and is not visible.
