Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
(2016)Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured ... -
Optical limiting properties of carbon disulfide at 2.05μm wavelength
(2016)Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. ... -
Optical parametric master oscillator and power amplifier for efficient conversion of high-energy pulses with high beam quality
(2004)We describe a system for parametric conversion of high-energy, Q-switched laser pulses from 1.064 µm to 2.1 µm in KTiOPO4. High beam quality and efficiency are obtained by use of a two-stage system: An optical parametric ... -
Optical parametric oscillators with high pulse energy and beam quality
(2010)A new method for obtaining high beam quality from high pulse energy optical parametric oscillators (OPOs) is demonstrated. By using different nonlinear crystals that have walk-off in orthogonal directions but are type 2 ... -
Optimal classification of standoff bioaerosol measurements using evolutionary algorithms
(2011)Early warning systems based on standoff detection of biological aerosols require real-time signal processing of a large quantity of high-dimensional data, challenging the systems efficiency in terms of both computational ... -

Optimisation of flare and chaff programs - an analytical approach
(2006)A statistical model is presented that expresses the mission survival probability of an aircraft as a function of various input parameters such as missile attack rate, false alarm rate, missile detection probability and ... -
Optimisation of performance-based continuation training – Study report for ANNC Collaborative Project between NLD and NOR – NLR Report TR-2021-172
(2021-09-10)This report documents the findings of a collaborative project within the Anglo-Netherlands-Norwegian collaboration (ANNC) between the Royal Netherlands Aerospace Centre (NLR) and the Norwegian Defence Research Establishment ... -
Optimization Model for Robust Acquisition Decisions in the Norwegian Armed Forces
(2013)The Norwegian Defence Research Establishment (FFI) supports the Norwegian Ministry of Defence with quantitative analyses for its long-term defence planning. As part of this activity, FFI has developed a stochastic model ... -
Optimization of active sonar parameters in a measured environment
(2021-09-13)ABSTRACT Sonar operation in coastal waters is challenging due to high false alarm rates and strongly varying sonar conditions. Optimal choices for sonar design and pulse characteristics depend strongly on target location ... -
Optimization of protocol operations in a Public Key Infrastructure
(2010)The protocol operations in a Public Key Infrastructure may be optimized in different ways. This report offers an introduction to the problem area, an analysis of the scalability properties of the relevant PKI operations, ... -
Optimization of training programs for competency-based training - COMFORT model description
(2020-01)The Royal Norwegian Air Force (RNoAF) is in the process of phasing in new F-35 combat aircraft, which will take on a wide range of roles. Efficient pilot training is crucial in order to make full use of this investment. ... -
Optimizing the troops-to-tasks problem in military operations planning
(2015)In the planning of military operations, deciding who should do what, where, and when is crucial for the success of the operation. This troops-to-tasks analysis is a project scheduling problem closely related to the ... -
The Optimum Dispersion of Carbon Nanotubes for Epoxy Nanocomposites: Evolution of the Particle Size Distribution by Ultrasonic Treatment
(2012)The ultrasonic dispersion of multiwalled carbon nanotube (MWCNT) suspensions was assessed by studying the differential sedimentation of the particles in an acid anhydride often employed as a curing agent for epoxy resins. ... -
Organizational flexibility from a network organizational perspective: a study of central predictors and moderating factors in military contexts
