OrganiCam is a laser-induced luminescence imager and spectrometer designed for standoff organic and biosignature detection on planetary bodies. OrganiCam uses a diffused laser beam (12° cone) to cover a large area at several meters distance and records luminescence on half of its intensified detector. The diffuser can be removed to record Raman and fluorescence spectra from a small spot from 2 m standoff distance.

The SuperCam instrument suite provides the Mars 2020 rover, Perseverance, with a number of versatile remote-sensing techniques that can be used at long distance as well as within the robotic-arm workspace. These include laser-induced breakdown spectroscopy (LIBS), remote time-resolved Raman and luminescence spectroscopies, and visible and infrared (VISIR; separately referred to as VIS and IR) reflectance spectroscopy. A remote micro-imager (RMI) provides high-resolution color context imaging, and a microphone can be used as a stand-alone tool for environmental studies or to determine physical properties of rocks and soils from shock waves of laser-produced plasmas.

Article Synopsis
  • Solid-state optical refrigeration utilizes anti-Stokes fluorescence to cool materials to cryogenic temperatures without vibrations, achieving notable results with Yb-doped YLiF crystals.
  • This study marks the first successful laser cooling of a connected payload, where a YLF:Yb crystal cooled a HgCdTe sensor to 135 K while integrated into a Fourier Transform Infrared spectrometer.
  • The cooling was made efficient by optimizing heat flow management, minimizing fluorescence heating, and ensuring reliable thermal connections, setting a foundation for the development of future optical cryocooler technology.
