1. A method for generating a region of plasma in an atmosphere, comprising the steps of:
- providing a gaseous atmosphere having argon as a constituent thereof;
directing a laser beam from a Ti;
sapphire laser into the gaseous atmosphere wherein at least a portion of the argon in the gaseous atmosphere along the laser beam is ionized; and
focusing microwave energy into the laser beam wherein the microwave energy interacts with the laser beam to generate a region of plasma.

Abstract
A method is provided for generating a region of plasma in a gaseous atmosphere that includes argon. A laser beam from a Ti:sapphire laser is directed into the gaseous atmosphere such that a portion of the argon along the laser beam is ionized. Microwave energy is directed into the ionized region of the laser beam to generate a plasma.
