Doppler-free spectroscopy of molecular iodine using a frequency-stable light source at 578 nm.

A stable light source obtained using sum-frequency generation (SFG) is developed for high-resolution spectroscopy at 578 nm. Hyperfine transitions of molecular iodine are observed by using the SFG light source with saturation spectroscopy. The light source is frequency stabilized to the observed hyperfine transition and achieves a stability of 2x10(-12) for a 1-s averaging time. The absolute fr...

Absolute frequency stabilization of diode-laser-pumped Nd:YAG lasers to hyperfine transitions in molecular iodine.

Diode-laser-pumped Nd:YAG lasers were frequency stabilized by locking their frequency-doubled output to Doppler-free absorption lines of the (127)I(2) molecule. The successive two-sample deviation of the beat frequency between two independent iodine-stabilized lasers is less than 650 Hz, or 2.3 x 10(-12) of the laser frequency, for averaging times between 24 and 80 s.

Extension of absolute-frequency measurements to the visible: frequencies of ten hyperfine components of iodine.

Direct-frequency measurements have been extended into the visible region of the electromagnetic spectrum. The visible frequencies were synthesized by generating the second harmonic of the recently measured 260-THz (20)Ne, 1.15-microm laser with a LiNbO(3) crystal. The absolute frequencies of ten hyperfine components of (127)I(2) near 520 THz are reported.

Absolute-Frequency Measurement of the Iodine-Based Length Standard at 514.67 nm

The absolute frequency of the length standard at 514.67 nm based on the molecular iodine ( I2) transition of the P(13) 43-0 component a3 is measured using a self-referenced femtosecond optical comb. This frequency-based technique improves measurement precision more than 100 times compared with previous wavelength-based results. Powerand pressure-related frequency shifts have been carefully stud...

Absolute Frequency Measurement of the Iodine-Stabilized Heâ‹TMNe Laser at 633 Nm

The absolute frequency of an iodine-stabilized He−Ne laser at 633 nm stabilized on the i (or a13) component of the 11-5 R(127) hyperfine transition of the I2 molecule is measured using a femtosecond optical comb generator and an iodine-stabilized Nd:YAG laser standard at 1064 nm. We link the measured absolute frequency to the current internationally adopted value via frequency intercomparison b...
