Abstract: Optopair for use in sensors and analyzers of gases such as methane, and a fabrication method therefor is disclosed. It comprises: a) an LED, either cascaded or not, having at least one radiation emitting area, whose spectral maximum is de-tuned from the maximum absorption spectrum line of the gas absorption spectral band; and b) a Photodetector, whose responsivity spectral maximum can be either de-tuned from, or alternatively completely correspond to the maximum absorption spectrum line of the absorption spectral band of the gas. Modeling the LED emission and Photodetector responsivity spectra and minimizing the temperature sensitivity of the optopair based on the technical requirements of the optopair signal registration circuitry, once the spectral characteristics of the LED and Photodetector materials and the temperature dependencies of said spectral characteristics are determined, provides the LED de-tuned emission and Photodetector responsivity target peaks respectively.

Abstract: An illumination system is disclosed for providing dual-excitation wavelength illumination for non-linear optical microscopy and micro-spectroscopy. The illumination system includes a laser system, an optical splitting means, a frequency shifting system, and a picosecond amplifier system. The laser system includes a laser for providing a first train of pulses at a center optical frequency ω1. The optical splitting means divides the first train of pulses at the center optical frequency ω1 into two trains of pulses. The frequency shifting system shifts the optical frequency of one of the two trains of pulses to provide a frequency shifted train of pulses. The picosecond amplifier system amplifies the frequency shifted train of pulses to provide an amplified frequency-shifted train of pulses having a pulse duration of at least 0.5 picoseconds.
