| Abstract: | XeCl laser pulse durations longer than 150 ns have been achieved by using a multiple stage L C sharpening circuit, increasing reflectivity of the output coupler, and adjusting concentration of HCl in the mixture of Xe/HCl/Ne. The longest pulse duration was up to 175 ns. The output energy per pulse was above 120 mJ. The study on optical fibers coupling of UV excimer laser was made . The coupling output energies of 0.4, 0.6, 0.8, and 1.5 (Diameter mm) UV silica optical fibers were 10, 29, 39, and 58 (mJ),respectively. It has made encouraging the first attempt for China-made excimer laser applications in laser-medicine field, particularly in laser angioplasty. |
