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.
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...
For optical packaging, there is a need to directly bond non-solderable materials such as oxides, nitrides, borides and fluorides, which are very difficult to wet/bond with low melting point solders, for example, at ~150°C or below. In this research, we describe new Pb-free universal solders with low melting point of 140°C or below by doping with a small amount of rare-earth elements, especially inexpensive...
In this paper we will discuss our development effort on a highly efficient master oscillator power amplifier (MOPA) laser transmitter for future space flight lidar missions.
In this paper we will discuss our development effort of a multi-beam airborne laser altimeter instrument as a pathfinder for the LIdar Surface Technology (LIST) mission.
We present the final configuration of the space flight laser transmitter as delivered to the Lunar Orbiter Laser Altimeter (LOLA) instrument. The instrument was launched in 2009 and has been in operation for close to two years and accumulated over 1.3 billion laser shots in space.
We report on progress in developing a new multi-beam non-scanning, swath mapping laser altimeter measurement approach for future spaceflight missions using a high repetition rate, short-pulse laser transmitter. The instrument contains multi pixel photon counting detectors, high bandwidth, sixteen-channel 8-bit digitizer and a high-throughput data system.
In this paper we will discuss our development progress on a non-scanning, swath mapping laser altimetry system. This paper will discuss the system approach, enabling technologies and instrument concept for the swath mapping laser altimetry.
The Lunar Orbiter Laser Altimeter (LOLA) is an instrument on the payload of NASA’s Lunar Reconnaissance Orbiter spacecraft (LRO) (Chin et al., in Space Sci. Rev. 129:391–419, 2007). The instrument is designed to measure the shape of the Moon by measuring precisely the range from the spacecraft to the lunar surface, and incorporating precision orbit determination of LRO, referencing surface ranges...
We present the final configuration of the space flight laser transmitter as delivered to the LOLA instrument. The laser consists of two oscillators on a single bench, each capable of providing one billion plus shots.
