Measuring the linewidth of a stabilized diode laser
Lal Muanzuala, Harish Ravi, Karthik Sylvan +1
We demonstrate a straight-forward technique to measure the linewidth of a grating-stabilized diode laser system---known as an external cavity diode laser (ECDL)---by beating the ou…

Optical frequency metrology with a Rb-stabilized ring-cavity resonator -- Study of cavity-dispersion errors
Alok K. Singh, Lal Muanzuala, Vasant Natarajan
We have developed a technique to measure the absolute frequencies of optical transitions by using an evacuated Rb-stabilized ring-cavity resonator as a transfer cavity. We study po…

Precise measurement of hyperfine structure in the state of Li using saturated-absorption spectroscopy
Alok K. Singh, Lal Muanzuala, Vasant Natarajan
We report a precise measurement of the hyperfine interval in the state of Li. The transition from the ground state ( line) is accessed using a diode laser a…
