Abstract
Third-order nonlinear optical susceptibility, chi((3)) of symmetricall y octa-substituted metal-free phthalocyanine thin films measured by th e third-harmonic generation technique are reported. The metal-free pht halocyanine has been found to show a chi((3)) (-3 omega; omega,omega, omega) value as large as 7.73 x 10-(12) esu at 1.80 mu m. The figure o f merit, chi((3))/alpha, was estimated to be 4.17 x 10(-17) esu cm at 1.05 mu m and 6.97 x 10(-16) esu cm at 1.65 mu m. Both linear and thir d-order optical properties of liquid-crystalline metal-free phthalocya nines are discussed.
