“…As an example, with a 25-μm thick Fabry-Perot etalon, we are able to select laser emission at 884 nm (16 mW of output power), at 891 nm (100 mW) or 899 nm (325 mW) [38]. However, the output power is reduced by a factor of two at 899 nm because of the additional losses introduced by the etalon.…”

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 diodepumped solid-state lasers for applications in the blue range, in replacement of gas lasers such as helium-cadmium lasers.

“…The lowest wavelengths ever reported with diodepumped solid-state lasers based on Nd ions are 903 nm with Nd:YLF [23], 900 nm with Nd:ASL [24,25], and re- cently 884 -899 nm in Nd:YAG and 879 nm in Nd:GdVO 4 [26,27]. In particular, the 4 F 3/2 -4 I 9/2 transition can offer other possibilities at lower wavelengths.…”

We report a diode-pumped Nd:YAG laser emitting at 899 nm based on the 4 F 3/2 -4 I 9/2 transition. A power of 1.04 W at 899 nm has been achieved in continuous-wave operation with a fiber-coupled laser diode emitting 19.2 W at 809 nm. Furthermore, intracavity second-harmonic generation in continuouswave mode has also been demonstrated with a power of 284 mW at 449.5 nm by using a BiB 3 O 6 (BiBO) nonlinear crystal. The fluctuation of the blue output power was better than 2.8%. The beam quality M 2 value is 1.3.

“…1). The lower wavelengths ever reported with diode-pumped solid-state (DPSS) lasers based on Nd 3+ ions are 899 nm with Nd:YAG [28]. Recently, the pure three-level laser reported based on Nd 3+ ions, for example, 880 nm [29] with Nd:YVO 4 , 879 nm [30] with Nd:GdVO 4 , and 869 nm [31] with Nd:YAG.…”

We report for the first time a Nd:LuVO 4 laser operating in a continuous wave (CW) on the true three-level laser at 880 nm, based on the 4 F 3/2 -4 I 9/2 transition. CW 345 mW output power at 880 nm is obtained under 18.2 W of incident pump power. Moreover, the intracavity second-harmonic generation (SHG) has also been achieved with a blue power of 37 mW by using a LiB 3 O 5 (LBO) nonlinear crystal. Output powers at 880 and 440 nm versus pump power at 809 nm
