  1. 1. Development and Application of Single-Ended Picosecond Laser Diagnostics

    Author : Billy Kaldvee; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Temporal Filtering; Picosecond Laser Diagnostics; Rayleigh Scattering; Laser-spectroscopy; DIAL; Laser Combustion Diagnostics; Lidar; Laser-induced Fluorescence; Laser-induced Incandescence; Fysicumarkivet A:2012:Kaldvee;

    Abstract : Light detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measurements, obtaining an ultimate range resolution of 0.

  2. 2. Laser diode systems for photodynamic therapy and medical diagnostics

    University dissertation from Department of Physics, Lund University

    Author : Eva Samsöe Andersen; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasi-phasematching; photodynamic therapy; laser-induced fluorescence; medical laser systems.; Histology; cytochemistry; histochemistry; tissue culture; Histologi; Laserteknik; Laser technology; cytokemi; histokemi; vävnadskultur; Diagnostik; Diagnostics; second harmonic generation; pulsed lasers; spatial filtering; Diode lasers; optical feedback; Fysicumarkivet A:2004:Samsöe Andersen;

    Abstract : This work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatment and to facilitate minimally invasive treatment.
