Description
Summary:We describe a spherical Fabry Perot etalon which is utilized as an internally coupled Fabry Perot Interferometer (icFPI). This icFPI uses piezoceramic translators for high frequency internal pathlength modulation and for controlled scanning of the icFPI cavity length. A tunable diode laser (TDL) is phase locked to the pathlength modulated icFPI, reducing laser phase noise and improving the precision of the wavenumber scale (in cm super(-1)). This stabilized laser system produces spectra with normal line shapes instead of first or second derivative line shapes normally associated with systems in which the laser emission wavelength is modulated in order to achieve stabilization. Line strengths of the super(13)C super(32)S sub(2), super(13)C super(33)S super(32)S and super(13)C super(34)S super(32)S isotopes of CS sub(2) were measured in the Delta v sub(3) identical with 1 fundamental region using the stabilized TDL system.
