  • Abstract
    A terahertz (THz) pulse laser with a wavelength of 385 μm is optically pumped by a transverse excited atmospheric CO2 laser based on three-level transition in D2O vapor. The used CO2 laser wavelength is 9.26 μm with an output peak power density of 3.0 MW/cm2. The 385 μm THz pulse signal was observed at different D2O vapor pressures. The energy of the THz pulse is performed as a function of the D2O vapor pressure, and a maximum THz pulse signal energy is obtained.
