Abstract

Absorption spectra obtained by intracavity laser spectroscopy (ILS) often contain fringe patterns that significantly mask absorption features and hamper the quantitative analysis of ILS data. Both the parasitic étalon fringes and the fringes that originate from spatially localized losses can be suppressed by a low-amplitude audio-frequency vibration of a folding mirror in the laser cavity. Using this methodology, we show that ILS spectra recorded with multimode lasers that contain nonideal intracavity surfaces have essentially no fringe contamination. The elimination of fringe contamination improves the detection sensitivity of ILS under normal experimental conditions and thus expands the potential for ILS applications.

Figures (4)

Fig. 1
Fig. 1

ILS instrumentation: the ILS laser cavity is formed by M1, M2, and M3. Electrical connections are depicted by filled half-circles, AOM 1 and AOM 2 are acousto-optic modulators, and M4 and M5 are mirrors.

Fig. 2
Fig. 2

Schematic representation of the piezoelectric unimorph and the modified folding mirror mount.

Fig. 3
Fig. 3

ILS spectra recorded by using three tg values (see panels) both with (solid curves) and without (dotted curves) folding mirror modulation. Fringes originate from a parasitic intracavity étalon.

Fig. 4
Fig. 4

ILS spectrum taken with (solid curve) and without (dotted curve) folding mirror modulation. In addition to the parasitic étalon fringes (as seen in Fig. 3), fringes that originate from spatially localized losses are also evident.
