Abstract A pulsed Nd:YAG laser at 355nm is used to pump Raman cell filled with D$_2$, D$_2$/Ar and D$_2$/He. With adequately adjusted parameters, the maximum photon conversion efficiency of the first-order Stokes light (S$_1$, 396.796nm) reaches 33.33% in D$_2$/Ar and the stability of S$_1$ in pure D$_2$ is fairly high, the energy drift being less than 10% when the pump energy drifts in the range of 5%. The conversion efficiency and stability, which are functions of the composition and pressure of the Raman medium and the energy of pump laser, are investigated. The result has been used to optimize the laser transmitter system for a differential absorption lidar system to measure NO$_2$ concentration profiles.

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.
