摘要：

We have determined the angular distribution of the fluorescence at 1051 nm wavelength of the Nd3+-doped monoclinic La2CaB10O19 crystal, originating from Nd3+ ions located in the regular La3+ sites, for extraordinary polarization in the XZ principal plane. We have found that the highest emission intensity does not occurs the Z-axis direction but in a -7.1 degrees around the Y=b-axis rotated direction. With a one-pump cavity we obtained simultaneous lasing at 1051 and 1069 nm in X and Z-polarizations from Nd3+ ions located in La3+ and Ca2+ sites, respectively. In the active Q-switch regime the two laser pulses are always simultaneous. With a two-pump setup based on an optical bifurcated fiber we obtained also simultaneous lasing at 1051 and 1069 nm. The relative power of the two laser channels is tuneable with the help of a beam-splitter. An adequate value of the relative pump power of the two channels leads to simultaneous pulses in the active Q-switch regime. (C) 2010 American Institute of Physics. [doi:10.1063/1.3503237]
