SUMMARY:Design and Testing of a Laser Thermal Propulsion Facility\, Ph
 ysics Department Colloquium\, Siera Riel \, REU student\,  McGill Univ
 ersity
DESCRIPTION:New developments in laser physics have recently steered th
 e discussion on alternative propulsion towards directed energy methods
 . In recent years\, phase-locked fiber optic lasers have been extensiv
 ely studied and appear to be promising methods of spacecraft propulsio
 n for inter-planetary and eventually interstellar missions. In compari
 son to CO2 lasers considered in the 1970s-80s\, the modularity and 1-Â
 µm operating wavelengths of fiber optic lasers allow their effective r
 ange to be extended by two orders of magnitude. They can be locked on 
 reflectors onboard a spacecraft and redirected to sustain an on-board 
 plasma core within a hydrogen heating chamber\, theoretically reaching
  specific impulse values of approximately 3000 s. The application of t
 hese modular arrays to laser-thermal propulsion (LTP) for short-term M
 ars missions thus provides an adequate platform to explore its utility
  in interstellar missions. This experiment aims to develop a multi-pur
 pose testing facility to investigate the thrust and thermal efficiency
  of an LTP system\, as well as the effect of gas seeding on these char
 acteristics.
