Infra-red multi-mode absorption spectroscopy of acetylene using an Er/Yb:glass micro-laser.
Multi-mode absorption spectroscopy, MUMAS, in the near-infra-red is reported for the first time. A diode laser pumped Er/Yb:glass micro-cavity laser emitting multiple longitudinal modes at 1.53 microm was used to detect several transitions in the nu(1)+nu(3) overtone band of C2H2.
