A scheme to generate terahertz (THz) emission using active disordered medium made of ruby grains with a three-level atomic system is proposed via a one-dimensional model. Our computed results reveal that THz random lasing phenomenon could occur under suitable conditions. The proposed scheme is based on the pumping of the 2 A ¯ level of ruby via a ruby laser operating on its R2 line (693.9 nm), and 0.87 THz random lasing is expected on the 2 A ¯ to E ¯ transition of the split E 2 level.
