Excess quantum noise in optical parametric chirped-pulse amplification.
Noise evolution in an optical parametric chirped-pulse amplifier (OPCPA) differs essentially from that of an optical parametric or a conventional laser amplifier, in that an incoherent pedestal is produced by superfluorescence that can overwhelm the signal under strong saturation. Using a model for the nonlinear dynamics consistent with quantum mechanics, we numerically study the evolution of e...
متن کاملNoncollinear Phase Matching in Optical Parametric Chirped-Pulse Amplification
Optical parametric chirped pulse amplication (OPCPA) is a method used to generate high-powered laser pulses. In this process, energy fiom a "pump" pulse is used to amplify a signal "seed" pulse. A computer program based on an analytical model was written and used to demonstrate the influence of noncollinearity, a condition in which the pump and seed are not parallel, and crystal tilt on the sig...
متن کاملDevelopment of Optical Parametric Chirped-Pulse Amplifiers and Their Applications
In this work, optical pulse amplification by parametric chirped-pulse amplification (OPCPA) has been applied to the generation of high-energy, few-cycle optical pulses in the near-infrared (NIR) and infrared (IR) spectral regions. Amplification of such pulses is ordinarily difficult to achieve by existing techniques of pulse amplification based on standard laser gain media followed by external ...
متن کاملFiber optical parametric chirped-pulse amplification in the femtosecond regime.
We study parametric amplification in optical fibers for chirped-pulse femtosecond laser systems. Compared to conventional OPCPA operating in bulk crystals, the fiber geometry offers a greater interaction length and spatial confinement, an increased flexibility in the choice of wavelengths for signal and pump beams, and the robustness of fiber setups. As opposed to rare-earth doped fibers, param...
متن کاملDesign constraints of optical parametric chirped pulse amplification based on chirped quasi-phase-matching gratings.
Chirped quasi-phase-matching (QPM) gratings offer efficient, ultra-broadband optical parametric chirped pulse amplification (OPCPA) in the mid-infrared as well as other spectral regions. Only recently, however, has this potential begun to be realized [1]. In this paper, we study the design of chirped QPM-based OPCPA in detail, revealing several important constraints which must be accounted for ...
