Saturated Amplification of a Collisionally Pumped Optical-Field-Ionization Soft X-Ray Laser at 41.8 nm

Abstract: We report the first saturated amplification of an optical-field-ionization soft x-ray laser. The amplifying medium is generated by focusing a circularly polarized 330-mJ, 35-fs, 10-Hz Ti:sapphire laser system in a few-mm cell filled with xenon. A gain of 67 cm(-1) on the 4d(9)5p-4d(9)5d transition at 41.8 nm in Pd-like xenon and a gain-length product of 15 have been inferred at saturation. This source delivers about 5 x 10(9) photons per pulse. The influence of the pumping energy and the laser polarization on … Show more

“…The ultrafast pumped optical field ionization (OFI) mechanism has been successfully shown for Pd-like Xe at 41.8 nm [5]. This was recently repeated by the LOA group in gain saturation regime for both the Pd-like Xe line [6] and the Ni-like Kr line at 32.8 nm [7]. A recent advance has been the use of higher order harmonics to seed the 32.8 nm OFI laser to boost the output and improve the x-ray laser characteristics [8].…”

“…This leads to a loss of efficiency and not the best use of the available pumping energy. Longitudinal schemes have a number of appealing characteristics and have been utilized in collisional excitation and recombination lasers [1,2,6,14]. The main advantages are the ability to create high irradiance short pulse pumping inside a capillary, for instance, where the electron density profile has been tailored.…”

“…Un tel système repose sur l'excitation collisionnelle électronique de gaz ionisés 8 fois par champ optique, nécessitant des intensités laser de 10 16 à 10 17 W/cm 2 . Récemment, la saturation de l'amplification de la raie à 41,8 nm du Xe 8+ a été observée [2][3][4], et le schéma OFI a été étendu au Kr 8+ avec l'obtention d'une raie lasante à 32,8 nm [5].…”

“…Suiteà la démonstration au LOA de l'amplification d'une raie laserà 41.8 nm dans le xénon IX et ensuiteà 32.8 nm dans le krypton IX [1,2], plusieurs expériences ont permis d'optimiser, caractériser et développer ce type de sources. Le milieu amplificateur est ici un plasma d'ions multichargés (Xe IX ou Kr IX) créé par la focalisation d'un laser intense (1J, 30 fs) dans un milieu gazeux.…”
