Second Harmonic Generation Lasers

Second Harmonic Generation Lasers

Second harmonic generation is the process by which two photons of the same wavelength are phase matched and summed to produce a single photon with twice the energy of the initial photon.  Since the energy of a photon is inversely proportional to the wavelength of the photon, this results in the conversation generation of light with half the wavelength of the initial output of second harmonic generation lasers.  The most common example of this process in laser technology is the abundance of 532 nm lasers.   An initial laser with a wavelength of 1064nm (typically Nd: YAG) passes through a non-linear crystal, and a portion of that light is converted to 532 nm.  Since second harmonic generation is a non-linear process depending on the intensity of the laser, not the power, pulsed lasers are commonly used as second harmonic generation lasers.  This results in a very high electric field density in the crystal, therefore, increasing the efficiency of the second harmonic generation process.  On this page, you will find a list of all the pulsed lasers we offer for second harmonic generation.
