A quartz capillary waveguide type H2 Eaman cell has been designed and investigated. Stimulated vibrational Baman scattering in H2 was studied by a 450nm dye laser pumping source. The Stokes-1 wave output energy was measured as a function of H2 pressure. The maximum energy conversion efficiency was 20%. The Stokes-3 pulse waveform was obtained by oxazine-1 dye laser pumping source and the maximum infrared Eaman output wavelength up to 6.57μm was obtained.
