Abstract

A single crystal-cored fiber using 4-(N, N-dimethylamino)-3-acetamidonitrobenzene (DAN) was fabricated. Single mode-propagation was achieved for dense flint glass cladding. The single ring-pattern of the second-harmonic wave corresponding to the singly guided fundamental mode was obtained and its conversion efficiency was 0.42% at the fundamental power of 29.3W. After collimation using an axicon lens, the second-harmonic wave from the fiber could be focused into a smaller spot than the usual light beam with a circular aperture.
