Chang, Q. Mao, S. Feng, J. Jiang, X. Li, Y. Tian, C. Xu, W. Liu] The tuning properties for the mid-IR DFG laser based on uniform grating PPLN have been investigated with tunable YDFL and EDFL fundamental lights. Our results show that, for a fixed crystal temperature, the idler tunable range is less than 10nm when the EDFL is tuned. Although the pump may be allowed to be tuned in its two QPM acceptance bands, the idler tunable range is still narrow for a fixed temperature. By optimizing the crystal temperature, however, the two pump QPM acceptance bands may be overlapped to form one broadband QPM band, which may be used to increase the idler tunable range to 175nm near 3.4μm region. The positions of the single signal and the two separate pump QPM acceptance bands can be continuously moved by adjusting the temperature, which may also be used for enhancing the idler tuning range. By tuning the EDFL while adjusting the temperature, a whole combined idler tuning range between 2.98 and 3.78μm was experimentally obtained with three fixed pump wavelengths of 1.05, 1.08 and 1.11μm. By tuning the YDFL in the two separate QPM acceptance bands, a tuning range of 690nm has been demonstrated with only one fixed signal wavelength of 1.58μm. Springer-Verlag, 2011 Chang J.
