| Abstract: | We report for the first time the spectroscopy and the laser operation of GdAl3(BO3)4: Nd3+ (NGAB) near 1338 nm corresponding to the 4F3/2→4I13/2 channel. Their features have been found favorable for self-frequency doubling in order to generate a red radiation at 669 nm and more generally for self-frequency conversions. The emission cross-section in σ-polarization was estimated to be 5.5×10−20 cm2. We demonstrated self-frequency doubling despite of non-optimal experimental conditions. |
