Optical parametric amplification (OPA) is an efficient approach of generating tunable pulses from a fixed laser source [4-6], including large energy fiber laser sources [7, 8].
Very recently, LGN exhibits a favorable set of optical properties for the application in mid-IR optical parametric amplification (OPA) [43] or optical parametric chirped pulse amplification (OPCPA) [44].

By controlling the power gain of the optical parametric amplification effect[4] from the optical signals, raising it when signals are weak and lowering it when signals are strong, the switch reduces optical noise without the need to convert optical signals into electrical signals.
[4] Optical parametric amplification effect: A type of nonlinear optical effect in which when a strong pump optical wave and signal optical wave are input into fiber, a new signal optical wave and idler wave are output.
It will be realized by means of a sequential two-stage optical parametric amplification scheme and allows to study novel effects induced by vibrational strong coupling with unprecedented structural and temporal resolution.
Optical parametric amplifications based on four-wave-mixing (FWM) in SOI waveguide have been theoretically investigated with the model of the coupled NLS equations describing the slowly varying amplitude of the optical waves [3-5].
