“…A tunable continuous-wave(cw) intracavity pump OPO based on multi poled period MgO:PPLN was reported. The 3.2-4.1 μm wide tuning mid-infrared parametric light was obtained by changing the poled periods and temperature 5 . Wang Peng reported a dual-wavelength mid-infrared laser based on intracavity difference frequency generation (DFG) in MgO:PPLN, which was pumped by a dual-wavelength fiber Optical Parametric Amplifier, the wavelengths of the mid-infrared output were 3.1 µm and 3.4 µm which the pumped wavelength were 1.06μm and 1.09μm 6 .…”

A compact dual wavelength Nd:YVO4/MgO:PPLN infrared laser was developed successfully which was composed of Nd:YVO4 crystal, MgO:PPLN crystal and a cavity mirror(M1). The fundamental laser was consisted of the first face of Nd:YVO4 and M1, and the optical parametric oscillation(OPO) cavity defined by the second face of Nd:YVO4 and M1. The infrared laser output with wavelengths of 1539 nm and 3447 nm was obtained using intracavity cw OPO technology. The output power of 1539nm and 3447nm were 670mW and 236mW at the pumped LD power of 6.0 W, and the optical conversion efficiency was 15.1%. The higher conversion efficiency was mainly attributed the 2mm thickness of MgO:PPLN crystal. Intracavity dual wavelength laser can be used in spectrum detection, drunk driving test and so on.

Objective Nanosecond midinfrared lasers with central wavelengths of 3 -5 µm are used in various applications, such as environmental monitoring, LIDAR , and electrooptical countermeasures, owing to the high atmospheric transmission at this band.Thus, developing highenergy midinfrared laser sources with high pulse repetition frequencies is crucial for practical applications because such lasers exhibit superior jamming effects and can effectively target an opponent's antijamming mechanism. An optical parametric oscillator (OPO) is suitable for efficiently realizing a tunable, highpulserepetitionfrequency laser owing to its compactness, wide tuning range, and high conversion efficiency. The output characteristics of an OPO are primarily determined by the optical properties of the constituent nonlinear crystals. Among the various nonlinear crystals used in OPOs, periodically poled magnesiumoxidedoped lithium niobate (MgO∶PPLN) has attracted considerable attention because of its large effective nonlinear coefficient, high damage threshold, and flexible phase matching ability. However, to date, a pulse energy of the order of hundred
