Field test of supercontinuum laser in atmospheric turbulence

Abstract

Supercontinuum laser has been paid more and more attention in recent years because of its wide spectral range and good directivity. Research on the transmission of supercontinuum laser in atmosphere is beneficial to its practical application. Supercontinuum generated by pumping a piece of photonic crystal fiber with output power of ~4.9W and generation directly in a random fiber laser with output power of ~2W were used in a 850 m transmission field tests respectively. The test was based on a Newtonian telescope to collimate and expand the laser, apply a real-time measurement of the ontarget power with an optical power meter at the receiving place. Experimental results show that the supercontinuum generated by random fiber laser can reduce the atmospheric impact more effectively than the other one.
