Wavelength swept amplified spontaneous emission source
... additional post-amplification can be used to provide sufficient levels of output power. The process of post-amplification of filtered ASE was demonstrated in a very rapidly swept laser source [12], where the tuning rate was above the single roundtrip limit and the laser did not have optical feedback ...

Demonstration of a multiwave coherent holographic beam combiner in a polymeric substrate
... In recent years there has been a keen interest in producing high-power lasers by using the method of beam combination. For some applications, such as a Doppler laser radar, it is necessary to ensure that the combined output is spectrally narrow. This requirement can be met by use of a coherent beam ...

... planes contribute to the scattering: thus the resolving power can become very large. At ESRF (ID16 and ID28) one performs X-ray scattering experiments with a resolution of 1 meV at an energy of around 20 keV. The limiting factor is here not fundamental, i. e. it is not dependent on how many contribu ...

Photonic Devices I Purpose of the Lab
... 1) Connect the DFB laser to the OSA. 2) The settings of the OSA may need to be changed to make the graph look nicer. It is recommended that the number of sampling points be set to 250. This can be done by pressing SETUP, followed by SAMPLING POINTS and then typing in 250 and pressing nm/ENTER. Try t ...
