“…The fine energy level structure of Nd 3+ ions, which has a stable four-level system, will be affected by different lattice sites. 12 Many dual-wavelength lasers have been achieved based on transitions between different energy levels of Nd 3+ ions. For example, the 1064 and 1318 nm dual-wavelength laser is based on Nd:YAP crystal, 13 the 912 and 1063 nm dualwavelength laser is based on Nd:GdVO 4 crystal, 14 and the 1074 and 1112 nm dual-wavelength laser is based on Nd:YAG crystal.…”

The orthogonal polarized dual-wavelength laser has attracted increasing attention due to its unique applications in spectral analysis, differential radar, terahertz, etc. In this paper, the Nd-doped LiY(MoO 4 ) 2 (LYMO) crystal with a disordered structure is selected as a laser gain medium to obtain the dual-wavelength laser. The fluorescence spectra of the Nd:LYMO crystal show obvious polarization anisotropy, which is caused by the anisotropic lattice field. The πand σ-polarized stimulated emission cross-sections at 1061 and 1068 nm are calculated to be 17.5

“…The dual-wavelength laser generation of Nd:YAG crystal has been investigated at the 4 F 3/2 → 4 I 11/2 and 4 F 3/2 → 4 I 13/2 transitions in many papers [12][13][14][15][16][17][18][19][20][21][22][23]. The dual-wavelength operation of Nd:YAG laser at the wavelengths of 1318 and 1338 nm is easy to obtain, since the values of the emission cross section for these transitions are very close [19][20][21][22][23].…”

Dual- and triple-wavelength diode-side-pumped electro-optically Q-switched Nd:YAG laser at 1318.8 nm, 1338.2 nm and 1356.4 nm with an intracavity etalon was demonstrated. The spectral composition of the generation was controlled by the rotation of the intracavity YAG etalon with a thickness of 100 µm. The experimental values of the tilt angle of the etalon for the laser generation with dual- and triple-wavelength output correspond well to the calculated values. When pumped by the electrical pulses with an energy of 8.7 J, triple-wavelength laser pulses with an energy of 96 mJ, a pulse duration of 37 ns, a peak power up to 2.6 MW and a repetition rate of 100 Hz were obtained. The proposed method of using an intracavity etalon allows to switch the spectral composition of the output radiation of Nd:YAG laser at 4F3/2 → 4I13/2 transition between single-, dual- and triple-wavelength modes.

“…The dual-wavelength generation was demonstrated in lasers based on different neodymium-doped active media, including isotropic crystals Nd:YAG [9][10][11][12][13], Nd:LuAG [14], Nd:GGG [15], Nd:GYSGG [16], Nd:CNGG [17], Nd:LaF 3 [18] and anisotropic crystals Nd:YVO 4 [19][20][21][22][23][24][25][26][27][28][29], Nd:GdVO 4 [30][31][32][33][34], Nd:LuVO 4 [35,36], Nd:YLiF 4 [37][38][39][40][41], Nd:LuLiF 4 [42], Nd:YAlO 3 [43][44][45][46][47][48], Nd:LYSO [49], Nd:LaBO 2 MoO 4 [50], Nd:LSB [51]. Dual-wavelength lasers with isotropic active media usually utilize specially designed dichroic output couplers and/or spectrally selective Fabry-Perot etalons.…”

Polarization investigation of the emission spectrum of Nd ions at the 4 F 3/2 → 4 I 11/2 transition in the b-cut Nd 3+ :YAlO 3 crystal showed that this gain medium is promising for multiwavelength laser operation. A diode-pumped continuous-wave Nd 3+ :YAlO 3 laser with an intracavity retardation plate and a dichroic output coupler demonstrated dual-wavelengths operation at 1064.5 & 1072.6 nm and 1072.6 & 1079.5 nm, as well as triple-wavelengths lasing at 1064.5 & 1072.6 &1079.5 nm. Low intra-cavity losses in the retardation plate allowed achieving a high laser efficiency close to that of a single-wavelength laser. The output power of the triple-wavelength laser reached 1.75 W under a pump power of 6.7 W with a slope conversion efficiency of 32.3 %.
