Abstract
We show the generation of a strong phase-matched third harmonic in a simple parallel nematic liquid crystal cell. A single laser beam of femtosecond p ulses is used to deform the internal structure of the molecular orientation distribution, and to generate the third harmonic from the twisted structur e that is formed. Up to 10(-5) of the laser power was converted to the thir d harmonic, in a volume as small as 5 mu m(3). [S0031-9007(99)08859-6].
