1 December 1991 Laser guide stars for adaptive optics systems: Rayleigh scattering experiments
Author Affiliations +
Experiments have been conducted in the atmosphere above Mt. Laguna Observatory to measure the properties of laser guide stars. The experimental system consists of a high frame rate video camera which records the backscattered light from an Excimer laser working in the near-UV at 351 rim. The Mt. Laguna 1-meter telescope is used to both transmit the outgoing beam and to image the return beam. The outgoing laser pulse triggers a time-gated image intensifier within the video camera which, with an appropriately selected time delay, records a time slice of the backscattered return signal. Preliminary results from the experiment can be used to calibrate the laser power needed to operate a large ground-based adaptive optics telescope.
