“…This method of injection would benefit from development of optical parametric chirped-pulse amplification laser systems [22] that can deliver high power, short pulse lasers with great wavelength flexibility, and be seeded by a single laser system (e.g., with a Ti:sapphire oscillator providing phase stabilization) for synchronization. A first experimental test could be done with a simple frequency-doubled (e.g., Ti:sapphire, 0.4 µm) injection pulse delayed with respect to a (0.8 µm) pump pulse.…”

A method is proposed to generate femtosecond, ultra-low emittance (∼10 −8 m rad), electron beams in a laser-plasma accelerator using two lasers of different colors. A long-wavelength pump pulse, with large ponderomotive force and small peak electric field, excites a wake without fully ionizing a high-Z gas. A short-wavelength injection pulse, with small ponderomotive force and large peak electric field, co-propagating and delayed with respect to the pump laser, ionizes a fraction of the remaining bound electrons at a trapping wake phase, generating an electron beam that is accelerated in the wake.

“…Following this pioneering work, Mucke et al [100] have demonstrated a 4-stage KTP/KTA OPCPA, which produce a CEP-stable multi-mJ 1.5-µm~70-fs pulse based on the fusion of a diode-pumped solid-state (DPSS) femtosecond Yb:KGW MOPA system and picosecond Nd:YAG solid-state technology. Even if the abovementioned works show the ability of generating IR output energy reaches the multi-mJ level in OPCPA, OPCPA in general faces important technical challenges [42], such as the requirement of a specific pump laser, the difficulty in synchronization with an external pump laser, and the unwanted generation of parasitic superfluorescence accompanying the primary pulse in broadband high-parametric-gain configurations [105].…”

Abstract:Over the past decades, optical parametric amplification (OPA) has become one of the most promising sources of ultrafast Mid-IR laser, owing to its outstanding properties including ultrabroad bandwidth, superior tunability, good beam quality, and scalable energy. In this paper, we review the recent progress in ultrashort laser pulse generation via chirp manipulated OPA, which improves the energy scalability and gain bandwidth by strategically chirping both pump and seed pulses. The gain mechanism is theoretically analyzed and the OPA processes are numerically simulated. In addition, the concept is verified experimentally. Femtosecond pulses with hundreds of mJ are generated in a high energy dual-chirped-OPA (DC-OPA), and ultrabroadband µJ-level spectra supporting sub-2-cycle pulse durations are achieved in BBP-OPA. Furthermore, the obtained pulses show excellent tunability through the NIR to Mid-IR regions, which makes them a suitable seeding source for further amplification as well as powerful tools in various applications such as strong field physics, attosecond science, and ultrafast spectroscopy.

“…We will hold the quadratic term in A ϕϕ and only the constant term everywhere else in A. Consequently, terms A ϕs = A sϕ and A ϕi = A iϕ disappear. Thus the quadratic form reads 2 terms. They are difficult to handle, so we try the following approximation, with real variables p, q, x, and y…”

“…As optical parametric amplifiers rely on nonresonant nonlinear interaction, they can be utilized to amplify extremely wide bandwidth pulses. One of the most appealing applications of this phenomenon is the Optical Parametric Chirped Pulse Amplifier (OPCPA) [1,2] in which ultrashort pulses are stretched, amplified and then compressed again. The gain medium is typically pumped by a nanosecond second harmonic pulse from a Q-switched laser.…”

We analytically find an approximate BlochMessiah reduction of a noncollinear parametric amplifier pumped with a focused monochromatic beam. We consider type I phase matching. The results are obtained using a perturbative expansion and scaled to the high-gain regime. They allow for a straightforward maximization of the signal gain and minimization of the parametric fluorescence noise. We find the fundamental mode of the amplifier, which is an elliptic Gaussian defining the optimal seed beam shape. We conclude that the output of the amplifier should be stripped of higher-order modes, which are approximately HermiteGaussian beams. Alternatively, the pump waist can be adjusted such that the amount of noise produced in the higherorder modes is minimized.
