  1. 1. Modeling of optical microresonator frequency combs

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Michael Ekström; [2022]
    Keywords : Optical frequency combs; Nonlinear optics; Temporal cavity solitons;

    Abstract : An optical frequency comb is a structure of equidistant, coherent spectral components which can be thought of as a large array of individual phase-locked laser sources. Their utilization in precision spectroscopy garnering part of the 2005 Nobel prize, optical frequency combs constitute a relatively novel technology with a large number of potential and actual applications.

  2. 2. Modeling the cavity dispersion in cavity-enhanced optical frequency comb Fourier transform spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adrian Hjältén; [2018]
    Keywords : ;

    Abstract : Cavity enhanced optical frequency comb spectroscopy is a technique that allows for quick and sensitive measurements of molecular absorption spectra. Locking the comb lines of an optical frequency comb to the cavity modes of an enhancement cavity and then extracting the spectral information with a Fourier transform spectrometer grants easy access to wide segments of absorption spectra.

  3. 3. Near-infrared optical frequency comb Vernier spectroscopy in air and in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Maryam Fakhri; [2017]
    Keywords : ;

    Abstract : A Vernier spectrometer is built with a near-infrared mode-locked Er:doped fiber laser, a Fabry-Perot cavity with finesse of 1000, a diffraction grating and a photo detector. The optical cavity provides high sensitivity in absorption detection by enhancing the interaction length of the light with molecular species contained in the cavity. READ MORE

  4. 4. Implementation of continuous filtering frequency comb Vernier spectroscopy for continuous acquisition of spectra in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adam Edlund; [2017]
    Keywords : optical frequency comb; continuous filtering Vernier spectroscopy;

    Abstract : In this project laser absorption spectroscopy was performed on a flame in a Fabry-Pérot cavity, using an optical frequency comb. Optical frequency comb spectroscopy is a technique that allows broadband ultra-sensitive detection of molecular species in gas phase. READ MORE

  5. 5. Data acquisition system for optical frequency comb spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ragnar Seton; [2017]
    Keywords : DAQS; HITRAN; MATLAB; libmx; Fourier Transform Spectrometry; Real time data visualization;

    Abstract : The Optical Frequency Comb Spectroscopy (OFCS) Group at the Department of Physics at Umeå University develops new techniques for extremely high sensitivity trace gas detection, non invasive temperature measurements, and other applications of OFCS. Their setup used primarily for trace gas detection contains several components that have been developed in-house, including a Fourier Transform Spectrometer (FTS) and an auto-balancing detector.
