Femti år etter utsettingene av mysis (Mysis relicta) og firetornet istidskreps (Pallasiola quadrispinosa) i norske innsjøer: til gagn eller skade?
(Journal article; Peer reviewed, 2022)Krepsdyra Mysis relicta (mysis, pungreke) og Pallasiola quadrispinosa (firetornet istidskreps, heretter kalt pallasea) forekommer i Norge naturlig i noen innsjøer på Østlandet. Etter utsettinger i regulerte innsjøer i ... -
Femtosecond Cr2+-based lasers
(Journal article; Peer reviewed, 2015)We review a novel class of femtosecond Cr2+-doped ZnSe and ZnS lasers, which operates in a very important for applications wavelength range between 2 and 3.5 μm and which generates ultrashort optical pulses that are only ... -
Femtosecond Cr:ZnS laser at 2.35 µm mode-locked by carbon nanotubes
(Journal article; Peer reviewed, 2014)We report the solid-state Cr:ZnS laser mode-locked by CNT-based saturable absorber. The absorber was deposited on a protected silver mirror used as a high reflector mirror in a standard 250-MHz cavity with chirped mirror ... -
Femtosecond laser writing of the depressed cladding buried channel waveguides in ZnS crystal
(Chapter, 2018)We report the first direct laser-writing of buried channel waveguides in ZnS. A depressed cladding waveguide with propagation loss of 0.62 dB/cm at 1030 nm allowed to obtain spectral broadening under femtosecond-pumping ... -
Femtosecond Operation and Random Quasi-Phase-Matched Self-Doubling of Ceramic Cr:ZnSe Laser
(Chapter, 2010)A 100-fs Cr:ZnSe laser, based on a ceramic active medium, generates 100 mW at 215 MHz repetition rate around 2450 nm. Co-propagating second-harmonic pulse at 1225 nm is simultaneously generated due to random quasi-phase-matching ... -
Femtosecond operation and self‐doubling of Cr:ZnS laser
(Chapter, 2011)Prismless dispersion‐controlled Cr:ZnS laser generates first femtosecond (110 fs) pulses at 180 MHz repetition rate around 2400 nm with average power 200 mW. Copropagating second‐harmonic pulse at 1200 nm is simultaneously ... -
Femtosecond SESAM-modelocked Cr:ZnS laser
(Journal article; Peer reviewed, 2012)We report self-starting femtosecond operation of a 180-MHz SESAM-controlled prismless Cr:ZnS laser around 2400 nm at open air and room temperature. Dispersion compensation was achieved by a combination of bulk materials ... -
Fenchel Duality and a Separation Theorem on Hadamard Manifolds
(Peer reviewed; Journal article, 2022)In this paper, we introduce a definition of Fenchel conjugate and Fenchel biconjugate on Hadamard manifolds based on the tangent bundle. Our definition overcomes the inconvenience that the conjugate depends on the choice ... -
Fenestration of Today and Tomorrow: A State-of-the-Art Review and Future Research Opportunities
(Journal article; Peer reviewed, 2012)Fenestration of today is continuously being developed into the fenestration of tomorrow, hence offering a steadily increase of daylight and solar energy utilization and control, and at the same time providing a necessary ... -

Ferroelasticity, anelasticity and magnetoelastic relaxation in Co-doped iron pnictide: Ba(Fe0.957Co0.043)2As2
(Journal article; Peer reviewed, 2019)The hypothesis that strain has a permeating influence on ferroelastic, magnetic and superconducting transitions in 122 iron pnictides has been tested by investigating variations of the elastic and anelastic properties of ... -
Ferroelectric and dielectric properties of Ca2+-doped and Ca2+-Ti4+ co-doped K0.5Na0.5NbO3 thin films
(Journal article; Peer reviewed, 2020)Chemical solution deposition (CSD) of K0.5Na0.5NbO3 (KNN) thin films on silicon-based substrates is an interesting technology for fabrication of lead-free ferroelectric thin films. Here, we report on improved ferroelectric ... -
Ferroelectric Domain Engineering Using Structural Defect Ordering
(Peer reviewed; Journal article, 2022)Ferroelectrics have become indispensable in the development of energy-efficient oxide electronics. Their domain state is closely linked to the final device functionality, making domain engineering in technology-compatible ... -
Ferroelectric domain walls for nanotechnology
(Journal article, 2021)Ferroelectric domain walls have emerged as a new type of interface in which the dynamic characteristics of ferroelectricity introduce the element of spatial mobility, allowing real-time adjustment of position, density and ... -
Ferroelectricity in the multiferroic hexagonal manganites
(Journal article, 2015)Since their discovery in 1963 the hexagonal manganites have consolidated their role as exotic ferroelectrics with astonishing functionalities. Their introduction as room-temperature device ferroelectrics was followed by ... -
Ferskvandsfiskenes utbredelse og indvandring i Norge med et tillæg om krebsen – 100 år i 2018!
(Journal article; Peer reviewed, 2018)I 2018 er det 100 år siden et grunnleggende arbeid om innvandring og forekomst av ferskvannsfiskene våre ble utgitt. Hartvig Huitfeldt-Kaas la gjennom banebrytende forskning et solid grunnlag for mange av de temaene som ... -
