Optical gas sensors based on correlation spectroscopy using a Fabry-Perot interferometer
… by a Phase Sensitivity Detector the optimum mirror reflectivity is 0.41 regardless of the other parameters. Moreover using the convolution method the optimal FPI mirror reflectivity can be quickly evaluated. The method also gives us guidance on selecting the best bandpass filter for the …

Application of sensitive spectroscopic techniques to intramolecular dynamics and combustion kinetics
… low sensitivity of CRD in the UV (due to lower mirror reflectivity, R - 0.99) by removal of non-exponential contributions to the ringdown decay. We have also developed a novel fitting algorithm to accurately extract the ringdown decay time from the ringdown signal. The resulting sensitivity is …

Debris Characterization And Mitigation Of Droplet Laser Plasma Sources For Euv Lithography
… steppers is reflective optics with multilayer mirror coatings on each surface. The wavelength of choice is 13.5 nm determined by the optimum reflectivity of the mirror coatings. The light source required for this wavelength is derived from a hot-dense plasma produced by either a gas discharge …

Laser-induced plasmas in air for pulsed broadband cavity-enhanced absorption spectroscopy
… time of light within the cavity, cavity mirror reflectivities may be calibrated in situ, thus facilitating measurements of absolute absorption coefficients with the intensity-dependent (IBBCEAS) approach. Each of the two spectroscopic approaches are compared in terms of their overall …
