“…In addition, an IR highresolution acousto-optic programmable dispersive filter (DAZZLER) [41] is used for higher-order dispersion control. To guarantee a homogeneous pump profile free of hot spots, we relay-image the 10 mm diameter crystal rod in the Nd:YAG power amplifier onto the 10 mm thick KTP crystals in stages 3 and 4.…”

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.

“…Afin de contrôler spectralement les harmoniques et idéalement de pouvoir déplacer une harmonique donnée de 1.5 eV pour obtenir une accordabilité totale des harmoniques, nous avons utilisé un modulateur acousto-optique dispersif programmable (AOPDF) , connu sous le nom de « Dazzler », qui permet simplement et efficacement de modifier la phase spectrale du laser. Ce dispositif est généralement utilisé pour contrôler la phase spectrale et l'amplitude spectrale dans les chaînes lasers [3,4].…”

Résumé. Afin de contrôler la génération d'harmoniques d'ordreélevé dans des conditions optimisées, nous avons réalisé des expériences préliminaires de contrôle spectral et spatial du laser infrarouge. Nous avons démontré la possibilité de modifier la longueur d'onde des harmoniques grâceà la modification de la phase spectrale du laser infrarouge par un modulateur acousto-optique « Dazzler ». Nous montrons que cette méthode permet d'obtenir un spectre plus large et un flux de photon intégré beaucoup plus important qu'en utilisant une simple modification de la dérive de fréquence du laser. Nous présentonségalement les premiers résultats de mise en forme de la tache focale du laser par optique adaptative, et l'effet de ce contrôle spatial sur la génération d'harmoniques.

“…Acousto-optical delay lines (AODL) are almost ideal adaptive devices for independent and simultaneous control of both amplitude and phase of spectral components of femtosecond laser pulses [1][2][3][4][5]. An AODL operates on the principle of light diffraction by ultrasound waves in birefrigent crystal.…”

The paper is devoted to investigation of adaptive optical delay lines, intended for femtosecond pulse shaping. Experiments were performed in the sub PW laser system, based on optical parametrical chirped pulse amplification. The experimental device has revealed high spectral resolution (0.6 nm at 1250 nm) high efficiency, (70% over a 120 nm spectral width at 1250 nm) and flexibility of seed pulse amplitude control. Proper shaping of the transmission function of adaptive optical delay line allows to double the femtosecond pulse spectrum band width.
