  3. 3. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

  4. 4. Evaluation of cluster based Anomaly detection

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Ajay Sreenivasulu; [2019]
    Keywords : Clustering; Unsupervised; Evaluation;

    Abstract : Anomaly detection has been widely researched and used in various application domains such as network intrusion, military, and finance, etc. Anomalies can be defined as an unusual behavior that differs from the expected normal behavior. READ MORE

  5. 5. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Zeyneb Alsadi; [2019]
    Keywords : DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Abstract : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. READ MORE
