A high stability semiconductor laser system for a $^{88}$Sr-based optical lattice clock [PDF]
, 2010 We describe a frequency stabilized diode laser at 698 nm used for high resolution spectroscopy of the 1S0-3P0 strontium clock transition. For the laser stabilization we use state-of-the-art symmetrically suspended optical cavities optimized for very low ...

A gas-jet apparatus for high-resolution laser spectroscopy on the heaviest elements at SHIP
, 2020 Laser spectroscopy enables the determination of fundamental atomic and nuclear properties with high precision. In view of the low production rates of the heaviest elements, a high total efficiency is a crucial requirement for any experimental setup to be

Application of spectral phase shaping to high resolution CARS spectroscopy [PDF]
, 2008 By spectral phase shaping of both the pump and probe pulses in coherent anti-Stokes Raman scattering (CARS) spectroscopy we demonstrate the extraction of the frequencies, bandwidths and relative cross sections of vibrational lines.

Laser spectroscopy of gas confined in nanoporous materials
, 2009 We show that high-resolution laser spectroscopy can probe surface interactions of gas confined in nano-cavities of porous materials. We report on strong line broadening and unfamiliar lineshapes due to tight confinement, as well as signal enhancement due

Probing QED and fundamental constants through laser spectroscopy of vibrational transitions in HD+ [PDF]
Nature Communications, 2016 The simplest molecules in nature, molecular hydrogen ions in the form of H2+ and HD+, provide an important benchmark system for tests of quantum electrodynamics in complex forms of matter.

A single hollow beam optical trap for cold atoms [PDF]
, 2001 We present an optical trap for atoms that we have developed for precision spectroscopy measurements. Cold atoms are captured in a dark region of space inside a blue-detuned hollow laser beam formed by an axicon.

Lifetime Measurement of Cesium Atoms Using a Cold Rydberg Gas
Applied Sciences, 2022 The lifetimes of nS1/2 and nD5/2 (n = 60–83) cesium Rydberg states are measured accurately in a magneto-optical trap using the field ionization technique and analyzed with the existing theoretical model. The room temperature blackbody radiation (BBR) and
