Nonlinear crystals: are they magic? [PDF]

open access: yesOptica Pura y Aplicada, 2015
Producción Científica The photograph shows a laser based only on nonlinear crystals. This kind of crystals employs the nonlinear answer of a medium to high power electromagnetic fields, in order to generate new frequencies. Via sum and difference of frequencies it is possible to extend the wavelengths of the existing lasers to others required by the ...
