ABSTRACT:
A circular bore transversely excited gas discharge laser is disclosed which may be constructed and operated with no physical contact between the active discharge and the metal excitation electrode structure. The discharge is excited by RF in the frequency range 10 MHz to 1 GHz applied to a transverse metal electrode structure designed to maintain a relatively uniform electric field in the discharge bore. The disclosed laser may be configured as a waveguide laser or a large bore laser operating in a non waveguide mode.
A means for inductively coupling RF energy from a suitable RF energy source to the electrode structure and a means for attaching mirrors to the discharge tube using no organic sealing material is disclosed. Without physical contact between the active discharge and the metal excitation electrode structure or organic sealants, long lifetime, superior laser performance, and capability for liquid cooling of the discharge tube is achieved.
