We are developing a multi-wavelength laser for the two-step laser time-of-flight mass-spectrometer (L2MS). The L2MS is designed to detect hydrocarbons in organically-doped analog minerals, including cryogenic Ocean World-relevant ices and mixtures for future astrobiology missions.
We describe an etalon spectrometer with a novel light recirculation scheme to generate simultaneous parallel wavelength channels with no moving parts. We present results from a system to resolve the 1651 nm absorption feature of methane. We present results from a prototype and a corresponding model. We also show results from a solid, 3-mirror etalon that has >95% peak transmission and significantly...
The advent of several key enabling electro-optics technologies afford advanced, non-topographic remote sensing instruments for space. We will present progress on several new, space-based laser instruments that are being developed at NASA GSFC. Long Abstract: In the past 20+ years, NASA Goddard Space Flight Center (GSFC) has successfully developed and flown lidars for mapping of Mars, the Earth, Mercury...
