For interferometric measurement methods such as optical white light interferometry, the coherence length of the implemented broadband light source is of central importance in order to realize a high axial resolution as well as a large dynamic range of the measurement system. In the case the broadband light sources are spectrally resolved by a spectral dispersive element, the spatial coherence and emission duration define primarily the coherence of the light source when no stimulated emission occurs. Broadband light sources with a high brilliance, such as supercontinuum and laser-driven plasma light sources, are particularly interesting for interferometric measurement methods because of their high spectral width and beam quality with enormous spectral power density. Especially for interferometric measurements, the coherence of the light source is essential. In the scope of the investigations, the coherence length and spectral power density of highpower supercontinuum light source based on a Yb-doped photonic crystal fiber in a nonlinear fiber amplifier setup and a commercially available laser-driven plasma light source were comparatively investigated with conventional white light sources. It was shown that the investigated high-power supercontinuum light source can be used very well for interferometric investigations. Furthermore, the achieved spectral pulse peak power densities exceed the laser-driven plasma light sources by a factor of one million.

“…Alterações na configuração do sistema, como por exemplo diferentes fontes de luz, potência da fonte e transmitância do frasco reacional podem desempenhar um papel decisivo na determinação da dose de luz entregue às moléculas receptoras. 128 A variação da energia do pulso do laser foi utilizada para identificação da dependência do número de fótons na degradação fotoinduzida. Entretanto, esse experimento só pôde ser realizado para BtP, visto que sua irradiação foi realizada utilizando um laser Quantel Brilliant acoplado à um oscilador paramétrico óptico (OPO) capaz de modular a energia do pulso e o comprimento de onda de excitação.…”
