摘要：

This paper gives an overview of the results obtained with diode-pumped Neodymium-doped crystals operating below 900 nm. Operation at such low wavelengths requires considering the strong thermal population of the lower level of the laser transition. Based on a theoretical study and simulations, the paper presents the challenges related to the design of these three-level lasers. Experimental results are given with Nd:YAG and Nd: vanadate crystals. It is explained how to deal with the line competition with emission at 946 nm or 912 nm. Finally, intracavity second-harmonic generation is presented. The output powers reach a few hundred mW at wavelengths below 450 nm. Hence, the paper demonstrates the potential of Nd-doped diode-pumped solid-state lasers for applications in the blue range, in replacement of gas lasers such as helium-cadmium lasers.
