13 September 2012An overview of guidestar laser technologies
We present a summary update of sodium laser guidestar technology, including an overview of the results from a series of
Laser Guidestar Workshops hosted by the Center for Adaptive Optics over the past few years. There has been
considerable advancement in the understanding of laser light interaction with mesospheric sodium which has an impact
on the choice of laser systems where the objective is to produce the best wavefront measurement with a minimum of
laser power and expense. We will also summarize our efforts on an NSF funded MRI program to build a high-Strehl AO
system for imaging and spectroscopy covering the near IR science bands from 0.9 to 2.2 micron wavelength. The system
includes a new 10 watt pulsed fiber laser developed by Lawrence Livermore National Laboratory tuned in spectral and
pulse format for optimum sodium return.
