Abstract

A tunable laser operating near 944nm is important for micro LIDAR systems. In this work, we have carried out a systematic study of Nd and Yb doped fiber glass materials which can be used for this purpose. The emission cross- sections of these materials at 944nm have been calculated. The wavelength dependence of emission of these materials has been studied. Among the silica based material Nd doped silica fiber glass has the largest cross section for 944 nm laser emission. The co-dopants reduce this cross section. Some Nd doped non-silica materials have higher stimulated emission cross section than silica based materials.
