We report the experimental characterization of the second harmonic generated in optically poled fibers. The fibers were poled by using both linearly and circularly polarized pumps at the wavelength of 1064 nm. Polarization and transverse profile of the light generated at 532 nm depend on the polarization of the input fundamental beam at 1064 nm used to pole the fiber. The generated second harmonic is carried by the LP01 mode if the fiber is poled only one time, whereas the second harmonic is carried by a combination of higher-order modes if the fiber undergoes the poling process more than once.

Abstract
We report the experimental characterization of the second harmonic generated in optically poled fibers. The fibers were poled by using both linearly and circularly polarized pumps at the wavelength of 1064 nm. Polarization and transverse profile of the light generated at 532 nm depend on the polarization of the input fundamental beam at 1064 nm used to pole the fiber. The generated second harmonic is carried by the LP01 mode if the fiber is poled only one time, whereas the second harmonic is carried by a combination of higher-order modes if the fiber undergoes the poling process more than once.File in questo prodotto:
