摘　　要：The temperature tuning of BaGa_(4)Se_(7)(BGSe)was demonstrated for the first time,to the best of our knowledge.When the temperature of BGSe(56.3°,0°)was raised from 30℃ to 140℃,the idler light under type Ⅰ raised from 3637 nm to 3989 nm,the tunable range reached 352 nm,and Δλ_(2)=ΔT reached 3.20 nm/℃.We calculated the phase matching curve of BGSe when Φ and T took different values.The relationship between θ and Δλ_(2)=ΔT was obtained by fixing Φ at 0°.The maximum Δλ_(2)=ΔT and its corresponding(θ,Φ)phase matching type were reported under different fixed λ_(2)(3μm,3.2μm,...,5μm).
