“…The wavelength tuning range was limited by the temperature dispersion and the grating period of the PPLN crystal and it will be further expanded by utilizing a PPLN crystal with multiple gratings 39) or fan-out grating. 40) When the SPP was reversed (the pump beam was lefthanded), the idler output was also left-handed, as evidenced by a pair of upward and downward Y-shaped fringes [Fig. 6(d)].…”

We propose a tunable millijoule-level 3-µm vortex laser formed with a 1-µm ns vortex pulse-pumped quasi-phase matching MgO-doped periodically poled lithium niobate (MgO:PPLN) optical parametric oscillator with a singly resonant plane-parallel cavity configuration. The wavelength of the vortex output is tuned within the range of 3.360-3.677 µm merely by controlling the temperature of the MgO:PPLN crystal. The maximum vortex output energy of 2.14 mJ is obtained at the maximum pump energy of 21 mJ, and corresponds to an optical to optical conversion efficiency of 10.2% and a photon conversion efficiency of 33.5%. The handedness of the vortex output is controlled just by inverting the handedness of the pump vortex beam.

“…Zi-Jian Wang, Yong-Ji Yu 1 , Rui-Zhi Zhai, Xin-Yu Chen, Chun-Ting Wu and Guang-Yong Jin 52 kHz, an average power of 9.23 W, and a pulse width of 19 ns achieved at 3.82 μm. In 2011, Xiong et al [18] presented a pump-enhanced singly-resonant OPO (PE-SRO) using a fanout PPMgLN crystal; when the repetition rate was 10 kHz and pump power was 22 W, a maximum output power of 3.4 W at 3781 nm mid-infrared laser was obtained. So, compared to previous research, improving the repetition rate and decreasing the pulse width can provide higher peak power mid-infrared laser output.…”

This paper reports a narrow pulse width optical parametric oscillator (OPO) based on periodically poled MgO:LiNbO 3 (PPMgLN). When the maximum pumping power of the 1064 nm laser was 26.07 W, the acousto-optical (AO) Q-switch repetition rate was 70 kHz and the PPMgLN crystal grating period was 29 μm; a 3840 nm mid-infrared light output power of 4.86 W was obtained at 150 °C, corresponding to a pulse width of 9.56 ns. The optical-optical conversion efficiency was about 18.6%. In addition, by changing the temperature between 25 °C to 200 °C, a tunable mid-infrared wavelength of 3765-3974 nm output laser was achieved.
