摘要：

The fluorescence (excitation and emission) spectra of Nd3+ ions in gadolinium gallium garnet (GGG):Nd and GGG:Nd,Cr have been investigated in the spectral region of laser interest, F-4(3/2) --> I-4(11/2) transitions. Four sites, denoted as alpha, beta, gamma, and delta are present in GGG:Nd, while two additional sites, epsilon and zeta, appear in GGG:Nd,Cr crystals. Site selective excitation (by using a Ti-sapphire laser) has permitted to obtain the energy level values for each Nd3+ site. This information is necessary for making lasers with these materials. Thus, it has been determined that the gamma site is the responsible for laser action in the GGG:Nd minilasers.
