Potential NASA Commercial Applications: A narrow line width 2 micron source will have a significant market for LIDAR, RF Photonics and sensor applications. The users will be military, NASA, homeland security, cable television distribution and oil exploration industry. The total market for narrow line width ultrastable lasers is currently at tens of millions of dollars. Princeton Optronics will commercialize the product very soon after development. Potential Non-NASA Commercial Applications: High stability, narrow linewidth lasers has applications for LIDARs by NASA. Narrow linewidth lasers can be used for many other NASA applications including ranging, wavefront analysis, wind speed measurement, surface topography, atmospheric composition analysis and communications. They can be used for remote sensing for entry descent and landing of spacecrafts.
