标题： PULSE: The Palomar Ultraviolet Laser for the Study of Exoplanets

摘要： 用于系外行星研究的帕洛马紫外激光（PULSE）将极大地扩展PALM-3000的科学范围，PALM-3000是位于5米海尔望远镜上的设施级高对比度极端自适应光学系统。通过使用紫外激光测量望远镜孔径附近的主导高空间和时间阶数湍流，可以将极限自然导星星等从mV < 10提高到mV < 16，从而实现卓越的校正。作为任何大型望远镜激光自适应光学系统中提供最高近红外斯托瑞克比值的设备，PULSE独特地支持低质量及更遥远的年轻系外行星系统的光谱观测，这对于全面了解系外行星族群至关重要。 显示英文摘要

摘要： 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.
