Development of a CW 1140 nm Sodium Polychromatic Laser Guidestar Source

We discuss the development of an 1140 nm Vertical External Cavity Surface Emitting Laser (VECSEL) for use with a traditional sodium laser gudiestar at 589 nm as a sodium polychormatic laser guidestar (PLGS). Narrowband 1140 nm laser output power > 12W is shown and simulations are presented to show the expected return for a PLGS. Article not available.
