| 摘 要： | 利用光栅选支调谐的TEA CO2激光器作为泵浦源设计了高能量脉冲光泵浦太赫兹激光器。太赫兹激光谐振腔由2m长的石英玻璃管、GaAs泵浦光输入窗和SiO2太赫兹光输出窗组成,氨气充入谐振腔内作为增益介质。太赫兹激光的波长由自主设计的金属线栅F-P干涉仪测量。实验中在多个波长处都获得了强烈的太赫兹光输出,其中151.5μm太赫兹光的输出脉冲能量高达204mJ,对应的泵浦光能量为32J。最后,还给出了利用151.5μm太赫兹光进行透视成像的实验结果。

| Abstract: | An optically pumped pulsed terahertz laser is presented.The pump laser is a line-tunable TEA CO2 laser.The terahertz cavity consists of a 2 m-long quartz glass tube,a GaAs input coupler and a SiO2 output coupler,and is filled with ammonia gas as terahertz active medium.Intense terahertz radiation is emitted at different wavelengths from the terahertz laser.The terahertz wavelengths are measured by a Fabry-Perot interferometer which is composed of two metal grids.As high as 204 mJ pulse energy is obtained at... |
