Diode laser absorption spectroscopy provides a direct method of determinating species concentration and local gas temperature in combustion flames. Under microgravity conditions, diode lasers are particulary suitable, given their compact size, low mass and low power requirements. The development of diode laser-based sensors for gas detection in microgravity is presented, detailig measurement of molecular oxygen. Current progress of this work and future application possiblities for these methods on the International Space Station are discussed.
