An experimental study on a cylindrical multi-pass cell

Circular paraboloid reflection cell for laser spectroscopic trace gas analysis

“…Such cells rely on a circular arrangement of spherical mirrors. In some studies, multiple spherical mirrors were positioned on a circle in a concentric arrangement [11][12][13][14][15]. Recently, several research groups have introduced multipass cells consisting of only a single, circular mirror [16][17][18][19][20].…”
