高强度太赫兹发生器TERA-AX

商用Ti:S超快放大器泵浦的高强度THz脉冲辐射发生器。

  • > 1 uJ THz脉冲能量
  • <1 ps THz脉冲duraiton
  • 频率范围0.5-2.5 THz
  • 低温冷却的MgO:LiNbO3选件
  • 太赫兹时域光谱仪选件,具有通过USB接口和Windows软件进行的电光采样
  • 通过REUS系列或其他商用Ti:Sa放大器进行泵浦

THz非线性光谱可以提供原子、分子、固态基本共振的新信息。THz非线性测量需要高功率THz源。AVESTA超短THz脉冲产生器Tera-AX,提供nJ量级脉冲能量。Tera-AX需要使用飞秒Ti:S放大器泵浦,例如AVESTA的Regulus或Multus产品。其他商业化的飞秒激光放大器也可以作为Tera-AX泵浦源。Tera-AX可以用于THz非线性光谱,大尺寸THz成像,或其他需要高能量超短THz脉冲的THz光学应用。Tera-AX通过基于MgO:LiNbO3相位匹配光学校正产生THz,通过倾斜飞秒激光器脉冲前沿达到相位匹配条件,光学校正和倾斜飞秒脉冲达到最高的光—THz转换效率。

AVESTA还提供选配的EO-AX电光探测器,用于测量THz脉冲电场时间波形。通过将瞬态数据进行标准快速傅里叶变换,得到THz脉冲幅值和相位。
