2. Novel Technologies for Mode-Locking of Solid-State Lasers
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-formations. In addition, mode-locking by cascaded nonlinearities is explored.

5. Development and Application of Single-Ended Picosecond Laser Diagnostics
University dissertation from Luleå : Luleå tekniska universitetAbstract : 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.
