چکیده
1 Absolute frequency measurement of Mid Infrared secondary frequency standard at BNM-LPTF G. D. Rovera, , Member, IEEE and O. Acef Abstract|An absolute frequency measurement of a CO2=OsO4 secondary frequency standard, operating in the mid infrared, is reported. A brief description of the measurement chain linking this standard to a hydrogen maser evidences the critical points. The measured frequency stability shows that the measurement system reaches the icker oor of the frequency standard, below the 10 14 level.

Progress toward absolute frequency measurements of the 127 I2-stabilized Nd: YAG laser at 563.2 THz/532 nm
Progress on the development of a frequency chain devoted to the absolute frequency measurement of 127I2-stabilized lasers around 563.2 THz/532 nm is reported. The aim of this work is the improvement of the accuracy—by at least one order of magnitude—of the absolute frequency of this standard. The scheme is based on the frequency combination of two wellknown optical frequency standards, namely a...
متن کاملFrequency-comb-referenced molecular spectroscopy in the mid-infrared region.
A simple method for absolute-frequency measurements of molecular transitions in the mid-IR region is reported. The method is based on a cw singly resonant optical parametric oscillator (SRO), which is tunable from 3.2 to 3.45 μm. The mid-IR frequency of the SRO is referenced to an optical frequency comb through its pump and signal beams. Sub-Doppler spectroscopy and absolute-frequency measureme...
متن کاملMid-infrared tunable, narrow-linewidth difference- frequency laser based on orientation-patterned gallium phosphide
We report on the first characterization of orientation-patterned gallium phosphide (OP-GaP) crystals used to generate narrow-linewidth, coherent mid-infrared (MIR) radiation at 5.85m by difference frequency generation (DFG) of continuous-wave (cw) Nd:YAG laser at 1064nm and diode-laser at 1301nm. By comparison of the experimental absolute MIR efficiency versus focusing to Gaussian beam DFG the...
متن کاملA coarse-grained normal mode approach for macromolecules: an efficient implementation and application to Ca(2+)-ATPase.
A block normal mode (BNM) algorithm, originally proposed by Tama et al., (Proteins Struct. Func. Genet. 41:1-7, 2000) was implemented into the simulation program CHARMM. The BNM approach projects the hessian matrix into local translation/rotation basis vectors and, therefore, dramatically reduces the size of the matrix involved in diagonalization. In the current work, by constructing the atomic...
متن کاملFrequency-comb-based absolute frequency measurements in the mid-infrared with a difference-frequency spectrometer.
We demonstrate the possibility of extending the well-established metrological performance of optical frequency-comb synthesizers to the mid-IR region by phase locking the pump and signal lasers of a difference-frequency source to two near-IR teeth of an optical comb. An uncertainty of 800 Hz (1.1 x 10(-11)) in the absolute frequencies of CO2 transitions near 4.2 microm has been measured by cavi...
