Abstract

JAXA’s Martian Moons eXploration (MMX) mission is a project to explore the two moons of Mars, with the launch currently being scheduled for 2024. Part of the project is raman spectroscopy to investigate fingerprints of organic compounds. The green 532 nm laser is an adaption from EXOMARS’ raman laser, providing ⪆100 mW in a singlemode fiber at a spectral bandwidth ⪅10 pm. Solderjet bumping as a laser-based soldering and thus optics bonding technology has been employed for the attachment of all miniaturized components of the two-channel DPSS configuration with intra-cavity frequency conversion by means of a BBO crystal. The integration platform is a DCB substrate for thermal connection, the system including fiber-coupling fits into a butterfly-alike housing ⪅10e5 mm³ volume, and ⪅10 g mass. Stability of the soldered optics in the <10 arcsec range was proven also during thermal vacuum, mechanical and radiation testing for space conditions.
