Abstract Experiment on characterizing the laser-heated plasmas using Thomson scattering measurement has been carried out. An incoherent Thomson scattering system with a 90° scattering angle has been established. The influence of the gas density and the pumping laser energy on the temperature of the laser-heated plasma has been examined. The results show that the temperature of the laser-heated plasma increases with the increase of pumping laser energy and the plasma density, which agrees well with the explanation of inverse Bremsstrahlung absorption.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
