Sentence examples for parametric gains from inspiring English sources

We find optimal phase-matching conditions and calculate the parametric gains as a function of pump intensity and interaction length.

Parametric gain can be understood as a result of a negative resistance of the pumpistor.

The characteristics of the parametric gain bands agree well with the simulations.

It predicts that two pairs of parametric gain bands can appear.

Maximum-bandwidth 2P-OPAs are designed ensuring positive parametric gain, tunable gain spectrum, and robustness against ZDW fluctuations.

However, with the enhancement of gain-saturation the parametric gain decreases, the flat gain bandwidth becomes narrow and the noise figure also increases.

This simple yet practical method is useful when isolators are adopted for stimulated Brillouin scattering suppression but it comes with the expense of parametric gain.

In experiment, it benefits from the high peak pump power of the Ti: sapphire pulse laser, two pairs of parametric gain bands are observed.

A highly efficient theoretical formulation based on four-wave-mixing (FWM) is worked out to determine fiber׳s chromatic dispersion (D) profile which is used to optimise the gain-bandwidth and ripple of the parametric gain profile.

To do so we used: (i) a highly-nonlinear fiber (HNLF) as the parametric gain medium; (ii) a narrowband tunable intracavity filter; (iii) a high output coupling fraction from the feedback loop (up to 3 dB).

The laser cavity for multiwavelength idler outputs is constructed by a pumped highly-nonlinear dispersion-shifted fiber as parametric gain medium, two highly-reflective chirped fiber Bragg gratings (CFBGs) and a superimposed CFBG as comb-like filter.
