The study on THz light-waves in One-dimensional random media

The research on optical properties of the light-waves in random media has become research hotspot in laser physics. Many theoretical models have been developed to explain the experimental results. With the further research on the optical properties of the light-waves in different random media, the great importance of THz section is attached. We research on the THz light-waves in One-dimensional random media, and mainly focus on the Frequency spectrum and threshold property. The results show that each of these THz modes also has a typical threshold gain behavior and different threshold pumping rate.
