Our solar-pumped lasers laboratory was established to largely enhance both the collection efficiency and beam quality of present-day solar-pumped lasers, resulting in the following research highlights:


A significant advance in solar laser collection efficiency was achieved by our team in PROMES-CNRS in (2012)



Our research "Design of ultrahigh brightness solar-pumped disk laser" was selected by


Spotlight on Optics Sept.14, (2012), The Optical Society of America.




Our  research on the first TEM00 solar-pumped laser was reported by Senior Editor Gail Overton in World News:"Novel Lasers: Solar-Pumped Nd:YAG Lasers Getting Brighter" 


Laser Focus World, Dec. 9, (2013) 


Our research article "A 40 W cw Nd:YAG solar laser pumped through a heliostat: a parabolic mirror system" was highlighted by Laser Physics in (2013)
