Microwave electric field (MW E-field) sensing is important for a wide range of applications in
the areas of remote sensing, radar astronomy and communications. Over the past decade …

A comprehensive study of three-photon electromagnetically induced transparency (EIT) and
absorption (EIA) on the rubidium cascade 5 S 1/2→ 5 P 3/2 (laser wavelength 780 nm), 5 P …

We report the measurement of absolute excitation frequencies of Rb 87 to n S and n D
Rydberg states. The Rydberg transition frequencies are obtained by observing …

Three-photon laser excitation of Rydberg states by three different laser beams can be
arranged in a starlike geometry that simultaneously eliminates the recoil effect and Doppler …

We demonstrate resonant detection of rf electric fields from 240 to 900 MHz (very high
frequency to ultrahigh frequency) using electromagnetically induced transparency to …

Wavelength meters are widely used for frequency determinations and stabilization purposes
since they cover a large wavelength range, provide a high read-out rate and have specified …

Present-day laser-spectroscopy experiments increasingly rely on modern commercial
devices to monitor, stabilize, and scan the wavelength of their probe laser. Recently, new …

A system of three external cavity diode lasers is used to excite Rydberg states in rubidium.
The 5S→ 5P→ 5D transitions are driven using lasers with λ= 780 and 776 nm respectively …

We report our measurements of the absolute transition frequencies of 5P_3/2, F= 3 to nS
and nD Rydberg states of 87Rb with high principal quantum numbers in a wide range of …

The spectra of the three-photon laser excitation 5 S 1/2→ 5 P 3/2→ 6 S 1/2 nP of cold Rb
Rydberg atoms in an operating magneto-optical trap based on continuous single-frequency …
