Paper Abstract

The work of Pique showed that multiple guidestars emitting at 1140 nm and 589 nm simultaneously could be utilized to correct for Tip and Tilt aberrations [1]. Such a guidestar is hence known as a PLGS (Polychromatic Laser Guidestar). However, no current high power (> 5W) narrow bandwidth (< 1GHz) exist for 1140 nm emission. A Vertical External Cavity Surface Emitting Laser (VECSEL) is shown with high power > 12W and narrow bandwidth emission which has been successfully used to pump the sodium 3P3/2 to 4S1/2 sodium transition as a testbed for the development of a CW PLGS system.
