Hydrogenated amorphous carbon synthesized from decomposition of liquid benzene by means of laser excitation of stimulated Brillouin and Raman scatterings in liquid benzene.

Synthesis of thin films of hydrogenated amorphous carbon has been obtained by using laser excitation of stimulated Brillouin and Raman scatterings in liquid benzene. As a matter of fact, above a threshold of the laser intensi ty, it is suggested that a strong shock-wave is generated in the liquid, wh ich is decomposed owing to the induced high dynamic pressure and temperatur e; at the same time, a film of hydrogenated amorphous carbon is deposited o nto the entrance window of the laser beam.
