“…The thermal tuning rate of the laser crystal is approximately 100 kHz/mW. 37 In order to efficiently couple light into the BUC, the laser frequency must coincide with a cavity transmission peak to within a small fraction of the transmission linewidth of the BUC. For a finesse of 6000 and a 6 GHz free spectral range, the spectral width of a cavity mode is 1 MHz.…”

A molecular beam spectrometer capable of achieving sub-Doppler resolution at 2 eV ͑ϳ18 000 cm Ϫ1 ) of vibrational excitation is described and its performance demonstrated using the CH stretch chromophore of HCN. Two high finesse resonant power-buildup cavities are used to excite the molecules using a sequential double resonance technique. A vϭ0→2 transition is first saturated using a 1.5 m color center laser, whereupon a fraction of the molecules is further excited to the vϭ6 level using an amplitude modulated Ti:Al 2 O 3 laser. The energy absorbed by the molecules is detected downstream of both excitation points by a cryogenically cooled bolometer using phase sensitive detection. A resolution of approximately 15 MHz ͑i.e., three parts in 10 8 ) is demonstrated by recording a rotational line in the vϭ6 manifold of HCN. Scan speeds of up to several cm Ϫ1 /h were obtained, with signal-to-noise ratios in excess of 100. The high signal-to-noise ratio and a dynamic range of 6ϫ10 4 means that future experiments to study statistical intramolecular vibrational energy redistribution in small molecules and unimolecular isomerizations can be attempted. We would also like to point out that, with improved metrology in laser wavelengths, this instrument can also be used to provide improved secondary frequency standards based upon the rovibrational spectra of molecules.

“…Wavelength tuning. -In order to change the emission wavelength within the fluorescence band, we used both a prism [27] and a grating [28]. As a prism we use a 600 sapphire prism, whose surfaces lie almost exactly at Brewster's angle when the prism is placed in the symmetrical position ; tuning can be accomplished by rotating the output mirror around a vertical axis.…”

“…At present, a commercial device is available which can be tuned from 2.2 to 3.2 pm with a singlefrequency output power of 5-50 mW using a krypton-ion laser pump. The high-resolution spectral properties of an F-centre laser have been looked at in detail by Beigang et al (1977) using a high-resolution Fabry-Perot spectrometer. A spectral width for a single mode was measured to be less than 260 kHz, while an estimate of the laser frequency fluctuations of 25 kHz was made by considering the contributions from thermal fluctuations of the temperature bath and pump power as well as mechanical fluctuations of the laser resonator.…”
