The 14th edition of the two-days workshop on Laser Technology and Systems for Adaptive Optics will take place in Marseille, France, kindly hosted by our friends of the Laboratoire d'Astrophysique de Marseille. 

The workshop brings world-experts on laser guide stars (researcher, students, industry professional, etc.) to present and discuss about the latest progress, ongoing issues, and future challenges around laser guide stars for adaptive optics.

We invite you to contribute to the workshop and submit an abstract with the topic your would like to present/discuss. The number of participants is limited to 50.
