This paper presents L-band ISAAC and NAOS/CONICA (VLT) spectroscopicobservations of the IRS~3-IRS~13 Galactic Center region. The ISAAC data allowedus to build the first spectroscopic data cube of the region in the L-banddomain corrected for the foreground extinction. Maps of the water ice andhydrocarbon absorption line strength were then derived. These maps areimportant diagnostics of the interstellar and circumstellar medium (resp. ISMand CSM). They support our previous results that the absorption features aremost probably occuring in the local Galactic center medium and can beassociated with the individual sources. Moreover, turbulence seems to affectthe studied region of the minispiral which appears like a mixture of a denseand diffuse medium. The Br alpha and Pf gamma emission line maps allowed us tofind three sources with broad lines corresponding to a FWHM deconvolved linewidth of about 1100 km/s and moving towards us with a radial velocity of about-300km/s. These sources are most probably new Wolf-Rayet type stars located inprojection to the north and west of IRS 3. Their derived radial velocities andproper motions show that only two of them might belong to the two rotatingdisks of young stars reported by Genzel et al. (2003) and Levin & Beloborodov(2003)...Comment: 12 pages, 11 figures and 2 tables. Accepted in A&
