摘　　要：The widely tunable and high resolution mid-infrared laser based on a BaGa_(4)Se_(7)(BGSe)optical parametric oscillator(OPO)was demonstrated.A wavelength tuning range of 2.76–4.64μm and a wavelength tuning resolution of about 0.3 nm were obtained by a BGSe(56.3°,0°)OPO,which was pumped by a 1064 nm laser.It is the narrowest reported wavelength tuning resolution for BGSe OPO,and was obtained by simultaneously controlling the angle and temperature of BGSe.
