“…9 In this letter, we demonstrate the generation of 0.4 mJ 11.5 fs laser pulses at 1.8 m. Similar to our recent work using the OPA Signal wavelength, 9 we spectrally broaden the Idler via nonlinear propagation in a HCF. Instead of chirped mirrors or adaptive devices for dispersion compensation, we show that laser pulses can be efficiently compressed utilizing solely the properties of fused silica ͑FS͒ in the anomalous dispersion regime below the third order dispersion ͑TOD͒ limit of bulk material.…”

“…Experiments were performed at the Advanced Laser Light Source (ALLS) at INRS-EMT using a Ti:Sapphire laser (Thales, 100 Hz, 80 mJ, 30 fs), which is described in [9,10]. The wavelength of the laser is shifted with an optical parametric amplifier (Light Conversion TOPAS-HE), broadened in a gas filled hollow fiber and then compressed with either chirped mirrors at 1.4 μm [11] or anomalous dispersion in fused silica glass at 1.8 μm [7]. The 7 mm diameter laser beam is focused with a 250 mm focal length spherical mirror, with an approximate f-number of 35.…”

High harmonic generation in gas targets leads to the production of attosecond pulses. The process of high harmonic generation requires that the gas be ionized by an intense femtosecond laser field. The highest photon energy produced is related to the laser intensity times the wavelength squared. This cutoff is reached only if good phase matching is achieved. Using a laser with a wavelength of 1800 nm, we estimate the laser intensity in the gas jet by recording the ion yield, and simultaneously record the high harmonic spectrum. We show that the cutoff energy matches the measured intensity, confirming that good phase matching is achieved to 100 eV. We also use the ion collector to characterize the spatial size of the gas jet and to measure the confocal parameter of the laser beam, parameters that are useful for numerical modelling.

“…Over the past decade, several pulse-compression techniques based on phase modulation induced by nonlinear optical effects have been developed extensively. One of the important methods to obtain compressed pulse is using self-phase modulation (SPM) in a gas-filled hollow fiber [1,2], a filament in gas cell [3,4], a fiber [5], or a bulk medium [6,7] to broaden spectrum and then compensating the spectral phase dispersion. This method is usually used to generate intense few-cycle pulses.…”

Simultaneous compression and amplification of a laser pulse in a glass plate

We demonstrated a novel method of simultaneous compression and amplification of a weak laser pulse in a glass plate using cross-phase modulation in conjunction with four-wave optical parametric amplification that was pumped by an intense femtosecond pulse. A proof-of-principle experiment succeeded in smooth broadening of the weak pulse spectrum by a factor of about three and simultaneously amplifying the pulse energy by more than three times. By using chirped mirrors to compensate the dispersion, the weak pulse was compressed from 22.6 fs to 12.6 fs. Furthermore, the output spectrum of seed pulse could be tuned by varying the delay of the intense pump pulse with respect to the weak seed pulse. This method can also be used for simultaneous spectral broadening of several weak beams with different wavelength at the same time.
