A Passively Wavelength-Stabilized Mid-Infrared Optical Parametric Oscillator

چکیده
High-power and widely tunable continuous-wave optical parametric oscillators (cw OPOs), as mature radiation sources in the mid-infrared range, are limited by their frequency fluctuation. We built a cw OPO working at near- ranges discuss extent to which its stability is affected mechanical temperature air pressure of cavity. In addition, we artificially provoked mode hops changing above two factors analyze thermal-induced refractive index variation crystal. An inequality between spacing free spectrum range (FSR) was observed. The wavelength guaranteed passively, longest mode-hopping-free time exceeded 13 h through sealing cavity thermal control. Further analysis affecting drift critically essential for reliability OPO, particularly environments outside laboratory, may provide new method high-precision tuning wavelengths.

Mid-infrared wavelength- and frequency-modulation spectroscopy with a pump-modulated singly-resonant optical parametric oscillator.
We describe the implementation of the wavelength- and frequency-modulation spectroscopy techniques using a singly-resonant optical parametric oscillator (OPO) pumped by a fiber-amplified diode laser. Frequency modulation of the diode laser was transferred to the OPO's mid-infrared idler output, avoiding the need for external modulation devices. This approach thus provides a means of implementin...

We demonstrate a two-crystal mid-infrared dual-wavelength optical parametric oscillator, synchronously pumped by a high power femtosecond Yb:fiber laser. The singly-resonant ring cavity, containing two periodically poled lithium niobate crystals, is capable of generating two synchronized idler wavelengths, independently tunable over 30 THz in the 2.9 4.2 μm wavelength region, due to the cascade...

متن کاملMid-infrared dual-comb spectroscopy with an optical parametric oscillator.
We present the first implementation of mid-infrared dual-comb spectroscopy with an optical parametric oscillator. Methane absorption spectroscopy was demonstrated with a resolution of 0.2 cm(-1) (5 GHz) at an acquisition time of ~10.4 ms over a spectral coverage at 2900-3050 cm(-1). The average power from each individual mid-infrared comb line was ~1 μW, representing a power level much greater ...
