Acoustooptic characterization of a birefringent two-mode photonic crystal fiber
Haakestad, Magnus Willum; Engan, Helge Emil (Journal article; Peer reviewed, 2006)The effect of axial variations in acoustooptic phase-mismatch coefficient of a two-mode birefringent photonic crystal fiber (PCF) is studied experimentally using two different methods. The first method is to determine axial ... -
Design of an End-Pumped Laser Source for Generation of High-Energy Nanosecond Pulses at 1.6 µm Wavelength
Klausen, Håkon Strand (Master thesis, 2015)A numerical model for simulating a pulsed laser has been implemented. The modelled laser can generate pulses with a duration of a few nanoseconds and a tunable wavelength. The laser consists of a diode-pumped neodymium-LiYF4 ... -
Development of a Long-Wave Infrared Laser Source Based on Optical Parametric Amplification in ZnGeP2
Bakkland, Ingrid Anette (Master thesis, 2016)This thesis presents the design and implementation of an 8 μm laser source based on nonlinear conversion in ZGP. ZGP is an attractive material for this purpose due to its high nonlinear coefficient, good transmission at ... -
Robust Identification of Concealed Dangerous Substances by Spectral Correlation of Terahertz Transmission Images
Rheenen, Arthur Dirk van; Haakestad, Magnus Willum (Journal article; Peer reviewed, 2015)Terahertz images containing spectral information in each pixel are recorded in transmission mode using a fibercoupled time-domain spectroscopy system. The images are acquired by mounting a sample holder on an x–y stage, ...
