Abstract
The fourth harmonic (266nm) of a pulsed Nd: YAG laser is used to pump Raman cells filled with D2 and D2/He. The dependences of the energy conversion efficiency of stimulated Raman scattering radiations upon the system parameters such as the pump energy pressure of pure D2 and partial pressure of He in D2/He mixture were experimentally studied. The maximum energy conversion efficiency of the first Stokes radiation (S1, 289.O4nm) reaches 22.1% in D2/He. The conditions to improve the energy conversion efficiency of Si were found. The results have been used to optimize the laser transmitter system for a S02 differential absorption lidar (S02-DIAL).
