Experimental study of a multipass gas cell with a variable optical pathlength for a THz absorption spectrometer

In this paper, the experimental study of a compact multipass cell prototype with a variable optical pathlength was conducted. The mechanism for varying the optical pathlength in the range from 0.51 to 2.46 m was implemented using a set of off-axis parabolic mirrors. To test the prototype, the cross-sectional profiles of experimental and theoretical THz beams for optical pathlengths of 0.51 and 2.46 m were compared. The experimental results confirm the viability of the developed multipass cell.
