“…An attempt to develop kilohertz subnanosecond OPO has been made recently by using periodically poled potassium titanyl phosphate crystal (PPKTP) [4], but this system is limited in terms of output energy and average power and no wavelength tunability was demonstrated. There have been studies with periodically poled lithium niobate (PPLN)-based OPOs in the mid-IR, which are either at high repetition rate (10 kHz) and very modest output energy (few microjoules) [5] or at low repetition rate (30 Hz) and high output energy (3.4 mJ), but consequently very modest average output power [6]. Additionally, the pump pulse durations that are usually used are above 10 ns, thus limiting the peak energy and power.…”

We report a subnanosecond mid-IR tunable optical parametric oscillator based on periodically poled stoichiometric lithium tantalate (PPSLT), pumped by an amplified single frequency microchip laser at 1064 nm at a repetition rate of 0.5 kHz. Using a 20 mm long PPSLT crystal polled with three different domain periods (30.2, 30.3, and 30.4 μm) and changing the temperature of the crystal from 20°C to 265°C, we achieved wavelength tuning between 2990 and 3500 nm. The high nonlinearity of the used medium and the large aperture (3.2 mm) ensure maximum idler output energy of ~2 mJ in the whole tuning range, corresponding to 18% idler conversion efficiency and more than 1 W of average power. 270 ps idler pulse durations were obtained as a result of the 818 ps pulse duration of the pump.

We reported a high-efficiency, broad-linewidth, wide-tuning-range singly-resonated optical parametric oscillator (OPO) based on a fan-out PPLT crystal. When the PPLT crystal was operated at 120 °C and pumped by Q-switched 1064 nm laser at 14.17 W with a circular pump profile, the overall output power of OPO was 7.22 W (η = 50.4%) for both the signal and idler waves. The central wavelength and linewidth of the mid-infrared (MIR) laser were 3770 nm and ∼40 nm. A wavelength tuning range of 3538–3941 nm was accomplished by adjusting the crystal period through simple mechanical movement. Due to the larger coverage of gratings with an elliptical pump profile, the output linewidth of the MIR laser was further broadened to ∼100 nm, which is ten times more than other non-fan-out PPLT OPOs. Both pumping methods with different profiles were operated at 30 kHz, 49.2 ns for the 1064 nm laser, the power fluctuation of the obtained MIR laser was within 3.5%.

“…Besides, tunable MIR laser sources with a repetition rate N10 kHz are also candidate sources for MIR countermeasures, i.e., jamming heat seeking missiles, in which high-repetition rate is necessary to jam effectively [12]. N. Dixit obtained 140 mW output power of 10 kHz pulsed idler at 3.47 μm with a pump power of 1.92 W using 1-mmthick MgO:PPLN [13]. P.D.…”
