Optical frequency comb spectroscopy.
Optical frequency combs offer enormous potential in the detection and control of atoms and molecules by combining their vast spectral coverage with the extremely high spectral resolution of each individual comb component. Sensitive and multiplexed trace gas detection via cavity-enhanced direct frequency comb spectroscopy has been demonstrated for various molecules and applications; however, pre...
متن کاملMultiplexed sub-Doppler spectroscopy with an optical frequency comb.
An optical frequency comb generated with an electro-optic phase modulator and a chirped radiofrequency waveform is used to perform pump-probe spectroscopy on the D1 and D2 transitions of atomic potassium at 770.1 nm and 766.7 nm, respectively. With a comb tooth spacing of 200 kHz and an optical bandwidth of 2 GHz the hyperfine transitions can be simultaneously observed. Interferograms are recor...
متن کاملOptical–optical double-resonance spectroscopy of autoionizing states of water
Double resonance excitation of vibrationally autoionizing states of the water molecule has been performed for the first time. Tunable, coherent vacuum ultraviolet light was used to excite selected rotational levels of the C̃ B1 state with one quantum of symmetric stretch vibrational energy ~100!, from which ~100! Rydberg states were excited with a second dye laser. The Rydberg character of the C̃...
متن کامل4Pg States of K2 by Optical–Optical Double Resonance Spectroscopy
Using a homemade ultrasensitive space charge limited ion detector, the K2 singlet gerade states (7–9Sg and 4Pg) were observed for the first time. The exotic potential of the double minimum 7Sg state was constructed using a hybrid approximation method. The molecular constants and the Rydberg–Klein–Rees (RKR) potential curve for the 9Sg state were obtained. The 8Sg and 4Pg states were partially c...
متن کاملMid-infrared dual-comb spectroscopy with an optical parametric oscillator.
We present the first implementation of mid-infrared dual-comb spectroscopy with an optical parametric oscillator. Methane absorption spectroscopy was demonstrated with a resolution of 0.2 cm(-1) (5 GHz) at an acquisition time of ~10.4 ms over a spectral coverage at 2900-3050 cm(-1). The average power from each individual mid-infrared comb line was ~1 μW, representing a power level much greater ...
