A compact vapor-cell optical frequency reference with fractional frequency instability around
Siqi Wu, Zhenqi Zhang, Xingyue Liu +12
Compact optical frequency reference with high stability is essential for field applications such as navigation and geodesy, yet vapor cell systems have remained confined to fractio…
Country wide Shared FibreBased Infrastructure for Dissemination of Precise Time, Coherent Optical Frequency with Vibration Sensing
Josef Vojtech, Tomas Novak, Elisabeth Andriantsarazo +16
With the increasing demand for ultra-precise time synchronization and frequency dissemination across various scientific, industrial, and communication fields, the Czech Republic ha…
Automatic unit for measuring refractive index of air based on Ciddor equation and its verification using direct interferometric measurement method
V. Hucl, M. Cizek, J. Hrabina +11
In scanning probe microscopy laser interferometers are usually used for measuring the position of the probe tip with a metrological traceability. As the most of the AFM setups are…
Absolute frequencies of H13C14N hydrogen cyanide transitions in 1,5 μm region with saturated spectroscopy and sub-kHz scanning laser
Jan Hrabina, Martin Hosek, Simon Rerucha +5
The wide span and high density of lines in its rovibrational spectrum render hydrogen cyanide a useful spectroscopic media for referencing absolute frequencies of lasers in optical…
Investigating the use of the hydrogen cyanide (HCN) as an absorption media for laser spectroscopy
Martin Hosek, Simon Rerucha, Lenka Pravdova +4
The laser spectroscopy is a fundamental approach for the realisation of traceable optical frequency standards. In the m wavelength band, widely used in telecommunications,…
Nonclassical light from large ensemble of trapped ions
Petr Obšil, Lukáš Lachman, Tuan Pham +7
The vast majority of physical objects we are dealing with are almost exclusively made of atoms. Due to their discrete level structure, single atoms have proved to be emitters of li…
Frequency tripled 1542 nm telecom laser diode stabilized to iodine hyperfine line in the 10-15 range
Charles Philippe, Rodolphe Le Tragat, David Holleville +6
We report on telecom laser frequency stabilization to narrow iodine hyperfine line in the green range of the optical domain, after a frequency tripling process using two nonlinear…
Optical phase locking of two infrared CW lasers separated by 100 THz
Nicola Chiodo, Frédéric Du-Burck, Jan Hrabina +3
We report on phase-locking of two continuous wave infrared laser sources separated by 100 THz emitting around 1029 nm and 1544 nm respectively. Our approach uses three independent…
CW frequency doubling of 1029 nm radiation Using single pass bulk and waveguide PPLN crystals
Nicola Chiodo, Frédéric Du Burck, Jan Hrabina +3
Following various works on second harmonic process using periodically poled Lithium Niobate crystals (PPLN), we report on the performances comparison between commercial bulk and wa…
