1. Backward and Forward Nonlinear Optical Processes in Potassium Titanyl Phosphate
Sammanfattning : Second-order nonlinear optical processes generate radiation across a broad spectrum, including UV and the far-infrared. In this thesis, new light sources in the near(NIR) and mid infrared (MIR) using three-wave mixing geometries in periodically poled potassium titanyl phosphate (PPKTP) is studied. LÄS MER
2. Fourier transform and Vernier spectroscopy using optical frequency combs
Sammanfattning : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

3. Laser spectroscopic analysis of atmospheric gases in scattering media
Sammanfattning : Laser spectroscopic techniques for gas analysis under various influences of light scattering are explored in a wide spectral range from the ultraviolet to the infrared. The techniques rely on spectrally narrow-band light sources that are used in differential optical absorption measurements. LÄS MER
