Abstract:

A carbon dioxide slab laser includes a top electrode and a bottom electrode. The top electrode has a socket formed at a geometric center and receives a contact ring in the recess of the socket. The contact ring includes radially inward extending biasing fingers. The biasing fingers contact a radio frequency (RF) energy feed through plug and engages the outer wall of the plug and retains it in the socket. The fingers disperse RF energy radially outward to the laser and provide for more even energy distribution that allows for more power. Grounding is also improved through grounding bars spaced apart longitudinally along the length of the bottom electrode. The transverse extending bars include contact elements having spaced apart fingers along the length of the contact element and providing multiple ground points to prevent focusing at a single grounding point.
