  1. Excimer Laser Progress Report Brendan Pratt University of Connecticut Advisor: Dr. Richard T. Jones

  2. Recap • Acquired all components required for initial testing. • Initial pulses showed lasing for approximately 5 minutes. • Discovered correct procedure for passivation from a Lambda Physik Engineer. • Duration of light produced from passivation indicates the quality of the laser system. • Laser intensity increased to 140mJ, but duration still lasted only 5 minutes.

  3. Plan of Attack • After talking with a local laser group, it was decided that the interior of the gas cavity may be contaminated. • We decided to undergo a major disassembly to remove any debris that could contaminate the fluorine gas.

  4. Inside the Gas Cavity

  5. Results • We have now seen red light for over 4 hours • The laser beam has not yet been profiled quantitatively. • However, lasing can be visually seen for over 25 minutes. • We plan to continue passivation procedures until we hit a limit.
