Phys. Rev. Lett. 97, 153901 (2006) [3 pages]Excimer Laser Pumped by an Intense, High-Energy Heavy-Ion Beam
High-energy heavy ions are an ideal tool to generate homogeneously excited, extended volumes of nonthermal plasmas. Here, the high-energy loss (dE/dx) and absolute power deposition of heavy ions interacting with matter has been used to pump an ultraviolet laser. A pulsed 70 MeV/u 238U beam with up to 2.5×109 particles in ∼100 ns beam bunches was stopped in a 1.2 m long laser cell filled with a 1.6 bar Ar-Kr-F2 mixture (typically 50%∶49.9%∶0.1%). Laser effect on the 248 nm KrF* excimer transition is clearly demonstrated. © 2006 The American Physical Society URL:
