摘要

基于D2O蒸汽中的三能级跃迁，利用横向激发大气CO2激光器光泵浦波长为385 μm的太赫兹(THz)脉冲激光器。所使用的CO2激光器波长为9.26 μm，输出峰值功率密度为3.0 MW/cm2。在不同的D2O蒸汽压下观测到385 μm太赫兹脉冲信号。将太赫兹脉冲的能量作为D2O蒸气压的函数，得到了最大太赫兹脉冲信号能量。

Optically Pumped Terahertz Laser Based on Three-Level Transition in D2O

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.
