DEVELOPMENT OF A HIGH ENERGY TI:SAPPHIRE LASER SYSTEM FOR THE EXCITATION OF EXTREME ULTRAVIOLET LASERS
Abstract: This PHD defense describes the design, construction and characterization of a high energy Titanium-Sapphire laser system for the excitation of Extreme Ultraviolet (EUV) lasers. EUV lasers have the potential to make possible a variety of new studies of surfaces and materials, and enable the development of unique metrology and processing tools for industry. Specifically the components developed to realize high energy operation as well as the development of a Nd:Glass zig-zag slab pump laser are discussed including results from new novel 800 nm multi-layer dielectric diffraction gratings for picosecond compression. Results from operation of the laser system with three different EUV lasers is presented including characterization of seeded operation of a EUV laser operating at 13.9 nm and an actinic imaging application capable of characterizing pattern and defect printability in extreme ultraviolet lithography masks with the Ni-like Cd laser operating at 13.2 nm.
