Second Harmonic Generation: Pathways of Nonlinear Photonics

Second harmonic generation (SHG) has a wide range of applications in today''s technological era, including nonlinear optics, quantum optics, lasers, material science, medical science, biological imaging, and high-resolution optical microscopy. In the laser industry, for example, SHG is prudent to create wavelength-specific high-energy lasers. It is also used to measure ultra-short pulse width with...
