The linewidth of the BaGa4Se7 (BGSe) optical parametric oscillator (OPO) was narrowed for first time, to best our knowledge, by inserting a Fabry–Perot (FP) etalon into an L-shaped cavity. When 15 mm long BGSe (56.3°, 0°) pumped 1064 nm laser, peak wavelength ∼3529 nm, and 4.53 (3.64 cm-1) under type I phase matching. After 350 µm thick FP etalon, decreased 1.27–2.05 nm. tilt angle 2.34°, 2.05 ...

Parametric resonance has been well established in many areas of science, including the stability of ships, the forced motion of a swing and Faraday surface wave patterns on water. We have previously investigated a linear parametrically driven torsional oscillator and along with other groups have mentioned applications including mass sensing, parametric amplification, and others. Here, we thorou...

Airy beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle manipulation, optically mediated particle clearing, long distance communication, and nonlinear frequency conversion. However, many of these applications including laser mach...

We present, for the first time to our knowledge, a cw, all-fiber optical parametric oscillator that uses a holey fiber. The oscillator operates at 1.55 microns and can yield an oscillating parametric signal that consists of a single line with a 30-dB extinction ratio and a 10-pm linewidth or that consists of multiple lines. In addition to the signal and the idler, five other pairs of spectral l...

We describe an optical parametric oscillator that is pumped by population-trapped atoms that are prepared with maximum coherence. The oscillator is based on the use of an effective nonlinear susceptibility that is of the same order as the linear susceptibility. Because the parametric gain is obtained in a single coherence length, the gain bandwidth can exceed the degenerate frequency. In Pb vap...
