D. C. Polarization in a Nonlinear Dielectric Medium at Optical Frequencies
Abstract
Investigation of nonlinear properties of materials at optical frequencies has ben made possible with the development of high power lasers. One of the nonlinearities encountered is the second order polarization in dielectric media that lack inversion symmetry. The second order nonlinear polarization gives rise to generation of second harmonic and d. c. components. The quartz crystal is chosen as the dielectric medium. By considering a suitable detecting system with a convenient configuration of the quartz crystal, it is shown that the output voltage of the detector is linearly proportional to the intensity of the laser pulse. Thus the possibility of using this principle to build a transmission type of meter of measuring power in high power laser pulses is presented.
