Optical Nonlinearity in DNA Films

Abstract

We have now measured second harmonic generation (1.06 micron source) in DNA films as a function of water content, and counter ion species. The OHG is weak, and does not vary systematically with water content or counter ion species. We have also measured the linear optical properties of DNA at high pressure, finding that electronic properties are very sensitive to pressure, a finding of importance in understanding the electronic basis of imaging of DNA in a scanning tunneling microscope. Keywords: Optical harmonic generation, DNA, Electronic properties, Biochemistry.
