Single- and multi-wavelength laser operation of a diode-pumped ND:GGG single crystal around 1.33µm

Laser diode end-pumped continuous-wave laser operation at 1339 nm in Nd : GGG with nearly diffraction-limited beam quality

“…double-walled carbon nanotube [24]. Other lasing wavelengths at 0.94 μm and its frequency doubling [25,26], 1.1 μm and its frequency doubling [27,28], 1.3 μm in continuous-wave, Q-switching and mode locking modes [29][30][31][32], as well as 1.4 μm in continuous-wave and Q-switching modes [33,34] have also been subsequently reported. The reason for the wide popularity of Nd : GGG as a laser gain medium can be summarized as follows.…”

“…Taking the excellent properties of Nd : GGG and the wide applications of the 1.3 μm laser into account, it is necessary to develop the 1.3 μm Nd : GGG lasers. Recently, we reported single-and multi-wavelength laser operation around 1.33 μm in a diode-pumped Nd : GGG [29]. In that work, some new lasing wavelengths have been achieved at 1324, 1337 and 1347 nm using a 0.1 mm glass etalon.…”

Continuous-wave dual-wavelength operation of a diode-pumped Nd:GdVO4 laser at the 1063 & 1071 nm, 1063 & 1083 nm and 1083 &1086 nm wavelength pairs

“…Dual-wavelength lasers have attracted a strong interest in recent studies due to their application in different areas such as terahertz imaging and spectroscopy [1,2]. Neodymium (Nd)doped solid-state laser crystals, which are well-known for their good spectral and mechanical properties, have proved to be great candidates for development of dual-wavelength lasers [3][4][5][6][7][8][9][10][11][12][13][14][15]. Generally, the standard emission line of the widely used Nd-doped solid-state laser crystals such as Nd:YAG, Nd:YVO 4 and Nd:GdVO 4 belongs to the 4 F 3/2 -4 I 11/2 intermanifold transitions.…”

Dual-wavelength synchronously mode-locked Nd:LaGGG laser operating at 1.3 μm with a SESAM

“…Factors such as the emission bandwidths inuence the mode-locked pulse characteristics much. As a derivative of Nd 3+ :Gd 3 Ga 5 O 12 (Nd:GGG) crystal, Nd 3+ :(La 0.1 Gd 0.9 ) 3 Ga 5 O 12 (Nd:LaGGG) not only has the similar properties with Nd:GGG such as good thermal properties, [6][7][8][9] but possesses the wider inhomogeneous broadened emission spectra due to the fact that a part of Gd 3+ ions is substituted with La 3+ in the crystal. Thus it offers an opportunity for Nd 3+ and the substitutive ions to enter 24c and 16a sites, which contributes to the more disordered structure.…”
