Paper Abstract
The Advanced Topographic Laser Altimeter System (ATLAS) will be the only instrument on the Ice, Cloud, and Land
Elevation Satellite -2 (ICESat-2). ICESat-2 is the 2nd-generation of the orbiting laser altimeter ICESat, which will
continue polar ice topography measurements with improved precision laser-ranging techniques. In contrast to the
original ICESat design, ICESat-2 will use a micro-pulse, multi-beam approach that provides dense cross-track sampling
to help scientists determine a surface's slope with each pass of the satellite. The ATLAS laser will emit visible, green
laser pulses at a wavelength of 532 nm and a rate of 10 kHz and will be split into 6 beams. A set of six identical,
thermally tuned optical filter assemblies (OFA) will be used to remove background solar radiation from the collected
signal while transmitting the laser light to the detectors. A seventh assembly will be used to monitor the laser center
wavelength during the mission. In this paper, we present the design and optical performance measurements of the
ATLAS OFA in air and in vacuum prior to their integration on the ATLAS instrument.
