WebSecond-harmonic generation is used by the laser industry to make green 532 nm lasers from a 1064 nm source. The 1064 nm light is fed through a bulk KDP crystal. In high-quality diode lasers the crystal is coated on the output side with an infrared filter to prevent leakage of intense 1064 nm or 808 nm infrared light into the beam. WebThe second harmonic generation (SHG) is one of the second order nonlinear optical phenomena that can occur in biological tissues, which contain chiral biological molecules such as collagen fibers. The optical coherence tomography (OCT) is a powerful technology that can produce high resolution cross-sectional images of biological tissues.
