Paper Abstract

This paper established a model of three-energy-level system from the laser rate equation theory, and then analyzed the molecular dynamic processes and laser mechanism of the optically pumped CH3OH. According to the experimental parameters, the CO2 laser is used to pump CH3OH to emit pulsed THz laser lines. When the 9P(36) line of CO2 laser pumps CH3OH, the 118.8 μm line radiation is obtained, and then we analyze the three-energy-level system’s the number of particles and the characteristics of the output waveform, and the influence of the pump light, buffer gas pressure and output coupler reflectivity on laser output power. The results show that this model reveals the generate terahertz optical pump laser process correctly.
