Generation of tunable EUV radiation
Abstract
X-ray lasers are a very useful tool producing a large quantity of data quickly and that can be used on many applications. Through seeding the X-ray laser (XRL) with a High Harmonic beam, the XRL will act as an amplifier of high-optical quality beam keeping the properties of the Harmonic while saturating at a shorter length. High Harmonics should however be tuned in order to match the wavelengths of the existing X-ray lasers. We present the results of the generation of tunable high-order harmonics by changing the pulse compression. We have obtained High harmonics up to the 51st order interacting a strong Nd-glass laser field with argon atoms in a gas cell. A shift of 13% around the central wavelength was observed allowing us to reach the Ne-like Mn and the Ne-like Fe lines via high harmonic generation (HHG). A study of the linear chirp was also performed.
