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 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 کاملDevelopment of cryogenically-cooled Yb:YLF chirped-pulse amplification laser for pumping few-cycle optical-parametric chirped-pulse amplification
As a pump source for intense few-cycle laser system with optical-parametric chirped-pulse amplification (OPCPA), we have been developing cryogenically-cooled Yb:YLF chirped-pulse amplification laser. So far we have successfully obtained high energy output pulse with 107 mJ of energy from a single-stage regenerative amplifier, which can be compressed to 2.2 ps in duration without pedestal. An ad...
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 ...
