TL;DR: In this paper, the absolute frequency of the optical clock transition 1S0(F = 1/2) −3P0( F = 1 /2) of 171Yb atoms confined in a one-dimensional optical lattice was determined to be 518.5(8.1)
Journal ArticleDOI
Sweep optical frequency synthesizer with a distributed-Bragg-reflector laser injection locked by a single component of an optical frequency comb
Seung-Nam Park,Eok Bong Kim,Young-Ho Park,Dae-Su Yee,Taeg Yong Kwon,Chul-Woung Park,Han Seb Moon,Tai Hyun Yoon +7 more
TL;DR: A sweep optical frequency synthesizer is demonstrated by using a frequency-stabilized optical frequency comb and injection-locked distributed-Bragg-reflector (DBR) laser diode.
Journal ArticleDOI
Dispersion-like signals in velocity-selective saturated-absorption spectroscopy
TL;DR: In this paper, the dispersion-like signal from a caesium-vapour cell configured for saturated-absorption spectroscopy was obtained from the difference in intensities of the two probe lasers passing through the vapour cell.
Journal ArticleDOI
Generation of 578-nm yellow light over 10 mW by second harmonic generation of an 1156-nm external-cavity diode laser
TL;DR: To achieve this result, a high power 1156-nm external-cavity diode laser is made with the maximum output power of more than 250 mW and will be used as a clock laser of the ytterbium optical lattice clock with robust and reliable operation.
Journal ArticleDOI
Transient coherence oscillation induced by a detuned Raman field in a rubidium Λ system
TL;DR: In this paper, the temporal evolution of coherent population trapping (CPT) was observed in rubidium atomic vapor when sudden changes were made to the detuning of a weak Raman field, and the subsequent creation and destruction of CPT are caused by the temporal oscillations of optically induced Raman coherence, with their period depending on the Raman detuning.
