This paper presents a detailed experimental study of random lasers with resonant feedback. The dependences of the lasing threshold and the number of lasing modes on the transport mean free path, the pump area, and the sample size are measured. An analytical model based on the concept of quasistates is developed to explain the behaviors of random lasers.
