摘要
:
Phase conjugated waves (PCW) were generated for the first time by degenerate four-wave mixing with subnanosecond laser pulses in potassium vapour near the D1 transition at 7699 Å. The light source was a long cavity grazing incidence dye laser. The pulses had a duration of 700-800 ps and a linewidth of 0.2 Å. The experiments were performed in a temperature range of 400-550° C. A maximum reflectivity of 57% has been observed together with temporal pulse shortening. PCW reflectivity has been measured as a function of the temperature, and the backward pump intensity. © 1990 Springer-Verlag.
