High-pulse-energy mid-infrared fractional-image-rotation-enhancement ZnGeP2 optical parametric oscillator
(2016)A high-energy mid-infrared ZnGeP 2 (ZGP) optical parametric oscillator (OPO) based on the nonplanar fractional-image-rotation enhancement resonator pumped by a 2.05 μm Ho 3+ :YLF laser is presented. Up to 120 mJ pulse ... -
High-pulse-energy, linear optical parametric oscillator with narrow and symmetrical far field
(2013)A new method to obtain a narrow and symmetrical far field from a high-pulse-energy optical parametric oscillator (OPO) with a linear resonator has been tested. The OPO employs two identical nonlinear crystals that are cut ... -
High-Resolution Neural Network Processing of LFM Radar Pulses
(2023-05-05)In radar applications, the bandwidth of a transmitted pulse determines the range resolution and the ability to disclose densely spaced targets. The processing of radar signals is often carried out through matched filtering ... -
High-resolution Spaceborne SAR Processing Using the Decomposed Transfer Function
(2017)In this paper a new analytic decomposed transfer function (DTF) for spaceborne SAR (Synthetic Aperture Radar) processing is calculated using the stationary phase approximation and Taylor’s series expansion. The DTF copes ... -
Holmium-doped fiber amplifier for pumping a ZnGeP2optical parametric oscillator
(2021-03-03)We present a holmium-doped all-fiber master oscillator power amplifier (MOPA) system operating at 2108 nm targeting optical frequency conversion applications. The MOPA delivers pulses of 0.52 mJ energy at 10 kHz repetition ... -
The Hotel Payload 2 campaign: Overview of NO, O and electron density measurements in the upper mesosphere and lower thermosphere
(2011)The ALOMAR eARI Hotel Payload 2 (HotPay 2) rocket campaign took place at Andøya Rocket Range, Norway, in January 2008. The rocket was launched on January 31, 2008 at 19:14 UT, when auroral activity appeared after a long ... -
How extending the kinematic model affects path following in off-road terrain for differential drive UGVs
(2022-05-31)Traversal in off-road conditions for Unmanned Ground Vehicles is highly relevant for defence applications, with an increasing amount of research being put into the field. A central part of the autonomous traversal is path ... -
How man-made interference might cause gas bubble emboli in deep diving whales
(2014)Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals. Necropsy results of the stranded ... -
How to assess good candidate molecules for self-activated optical power limiting
(2018)Reverse saturable absorbers have shown great potential to attenuate laser radiation. Good candidate molecules and various particles have successfully been incorporated into different glass matrices, enabling the creation ... -
Human performance research for military operations in extreme cold environments
(2020)Objectives Soldier performance in the Arctic depends on planning and training, protective equipment, and human physiological limits. The purpose of this review was to highlight the span of current research on enhancing ... -
Hva nå, norsk forsvarsindustri? Instrumentelle og institusjonelle svar på EUs nye politikk på det sikkerhets- og forsvarspolitiske området- Instrumentelle og institusjonelle svar på EUs nye politikk på det sikkerhets- og forsvarspolitiske området
(2019-12-11)Artikkelen diskuterer EUs nye forsvarspakke med særlig vekt på CARD (Coordinated Annual Review on Defence), PESCO (Permanent Structured Cooperation) og EDF (European Defence Fund). Formålet er å styrke EU som sikkerhetspolitisk ... -
