Phase to frequency conversion is demonstrated with a synchronously modelocked optical parametric oscillator, with a sensitivity of 16 MHz/radian, and a phase resolution of 9ldr10-8 radian.
We use low finesse Fabry-Perot cavities in series to generate frequency combs with large mode spacing by simultaneously maintaining high spectral bandwidth. The attenuation of laser modes closest to the pass band exceeds 70 dB relative to the modes centered within the pass band for a 5 GHz Fabry-Perot filtering a 250 MHz frequency comb.
An Yb-doped fiber laser and amplifier system is used together with an enhancement cavity for high harmonic generation for precision spectroscopy. Higher order harmonics can be produced in comparison to systems with Ti:sapphire lasers.
An enhancement cavity can optimally reshape the small-signal gain across the interacting pulses of a chirped-pulse parametric amplifier, increasing the gain bandwidth dramatically while simultaneously boosting the conversion efficiency.
We present a mid-infrared frequency comb based on a synchronously-pumped, femtosecond optical parametric oscillator. The idler (signal) is continuously tunable from 2.8-4.8 mum (1.76-1.37 mum) with a maximum average output power of 1.50 W.
We present a single-photon source based on cavity-enhanced parametric down-conversion with < 3 MHz linewidth and a brightness of 14000 counts/(s times mW times MHz). Measuring heralded single-photon statistics, we achieved a 100-fold suppression of two-photon events compared to a Poissonian source.
We theoretically demonstrate high fidelity frequency conversion of a photon generated by a dipole-like emitter in a double mode nonlinear cavity irradiated by a classical field, and propose a realistic photonic crystal nanocavity implementation.
