“…To obtain a relatively short IR pulse, a noncollinear OPCPA of 1.56-µm pulses using KTA is later proposed and demonstrated [104], in which 100-fs pulses from an erbium fiber laser were stretched to 100 ps and the KTA crystals were synchronously pumped by high-power 100-ps pulses from a Nd:YLF regenerative amplifier at 1.053 µm. This work opens the door for power scaling of OPCPA to simultaneously obtain a high peak power and an ultrashort pulse duration less than 100 fs.…”

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.

“…By using a fiber-doped laser system in combination with a powerful ps-solid-state laser system, parametric amplification of the near-IR radiation can be achieved, even above the mJ level. So far, near-IR OPCPA source at the 10-mJ energy-level have been reported [47,48] delivering pulses in the multi-cycle regime (∼200 fs) at repetition rate between 10 Hz and 1 kHz.…”

Abstract:Over the last few decades, the investigation of ultrafast phenomena occurring in atoms, molecules and solid-state systems under a strong-field regime of light-matter interaction has attracted great attention. The increasing request for a suitable optical technology is significantly boosting the development of powerful ultrafast laser sources. In this framework, Optical Parametric Amplification (OPA) is currently becoming a leading solution for applications in high-power ultra-broadband light burst generation. The main advantage provided by the OPA scheme consists of the possibility of exploring spectral ranges that are inaccessible by other laser technologies, as the InfraRed (IR) window. In this paper, we will give an overview on recent progress in the development of high-power few-optical-cycle parametric amplifiers in the near-IR and in the mid-IR spectral domain. In particular, the design of the most advanced OPA implementations is provided, containing a discussion on the key technical aspects. In addition, a review on their application to the study of strong-field ultrafast physical processes is reported.

“…Adding two OPCPA booster stages 3 and 4 allows us to reach pulse energies above 10 mJ. Following the pioneering work of Kraemer et al [37,38], we employ Type II phase-matching (e s + o i → o p , θ = 45.5 • , ϕ = 0 • ) in KTiOPO 4 (KTP) crystals (1.03 µm / 1.064 µm pump, ∼1.5 µm signal, ∼3.3-3.7 µm idler) for OPA stages 2-4 because these crystals (unlike borate crystals) are transparent for the mid-IR idler wavelength and exhibit a relatively broad bandwidth around 1.5 µm. Moreover, Type-II OPA minimizes parasitic self-diffraction [39].…”

We discuss a four-stage optical parametric chirped-pulse amplifier that delivers carrier-envelope phase-stable ∼1.5 µm pulses with energies up to 12.5 mJ before recompression. The system (previously reported in Opt. Lett. 34, 2498Lett. 34, (2009) is based on a fusion of femtosecond diode-pumped solid-state Yb technology and a picosecond 100-mJ Nd:YAG pump amplifier. Pulses with 62 nm bandwidth are recompressed to a 74.4 fs duration, which is close to the transform limit. Here, to show the way towards a TW-peak-power single-cycle IR source, we perform detailed investigations of single-filament IR supercontinuum generation via femtosecond filamentation in noble gases. Depending on the experimental conditions, two filamentation regimes can be achieved: (i) in the filamentation regime without plasma-induced pulse self-compression, we generate 4-mJ 600-nm-wide IR supercontinua of high spatial quality supporting 8-fs pulse durations, which corresponds to less than two optical cycles at 1.5 µm; (ii) in the self-compression regime, we demonstrate self-compression of 2.2 mJ pulses down to 19.8 fs duration in a single filament in argon with a 1.5 mJ output energy and 66% energy throughput. By adapting the experimental conditions, further energy upscaling of the self-compressed pulses seems feasible.
