Ultra-high precision comb-locked terahertz frequency-domain spectroscopy of whispering-gallery modes
Publikováno v:
APL Photonics, Vol 9, Iss 7, Pp 076109-076109-6 (2024)
We demonstrate the capabilities of a novel frequency-domain terahertz spectrometer based on a comb-locked frequency synthesizer, which provides absolute frequency calibration. The inherent stability and repeatability of the scans allow for the combin

In 2013, members of the terahertz community in Germany initiated the formation of VDI standards for terahertz systems. Since terahertz systems are associated with different research branches, the initiative serves, among other aspects, to develop a c

Optical Frequency Domain Reflectometry features high resolution and sensitivity. The resolution is limited by the laser scan range, linearity and noise. We introduce a laser source capable of precise > 10 THz wide and > 1 THz/s fast scans remaining p

We exploit a widely tunable comb-locked frequency-swept synthesizer to test a new optical approach to primary gas thermometry based on a global fitting of multiple molecular absorption lines of the same band at different pressures.

Due to the inherently low crosstalk between carrier-envelope and repetition rate control mechanisms, difference-frequency generated (DFG) optical frequency combs are an attractive light source for low-phase-noise microwave generation based on feedbac

In this paper we propose multispectrum rotational states distribution thermometry as an optical method for primary thermometry. It relies on a global fitting of multiple absorption lines of the same band at different pressures. The approach allows le
