  The Palomar Ultraviolet Laser for the Study of Exoplanets (PULSE) will
dramatically expand the science reach of PALM-3000, the facility high-contrast
extreme adaptive optics system on the 5-meter Hale Telescope. By using an
ultraviolet laser to measure the dominant high spatial and temporal order
turbulence near the telescope aperture, one can increase the limiting natural
guide star magnitude for exquisite correction from mV < 10 to mV < 16.
Providing the highest near-infrared Strehl ratios from any large telescope
laser adaptive optics system, PULSE uniquely enables spectroscopy of low-mass
and more distant young exoplanet systems, essential to formulating a complete
picture of exoplanet populations.
