Description

We are developing a technique for measuring gas pressure using laser induced plasmas (LIPs). To accomplish this, we are studying how various characteristics (e.g., emittance, and size) of LIPs vary as a function of pressure within a test chamber filled with known pressures of argon. This technique should allow measurements of pressure with spatial resolutions of less than 1 mm, without the presence of a physical probe that might disrupt the environment being studied. We will be presenting the preliminary results of our characterization of LIPs.
