We report the experimental realization of nonuniformly correlated partially coherent light (NUCPCL) beams by passing laser beams through a phase-only spatial light modulator. The characteristics of NUCPCL beams whose coherence is of Gaussian distribution as well as inverse Gaussian distribution are studied theoretically and experimentally. It is shown that the experimental observations are in agreement with our theoretical analysis. NUCPCL beams may have some applications in optical manipulation.

Based on a free-running diode-end-pumped a-cut Nd:YVO4 laser with output power of 3.61 W at a single wavelength of π-polarized 1342 nm, we further obtain a 1.82 W σ-polarized 1345 nm laser with a slope efficiency of about 22.3% by introducing an intracavity etalon, for the first time to the best of our knowledge. In addition, a simultaneous dual-wavelength orthogonally polarized laser at π-polarized 1342 nm and σ-polarized 1345 nm can also be achieved with a maximum output power of 1.35 W. The dual-wavelength laser provides a potential laser source for terahertz wave generation.
