Continuous tuning characteristics of a small high pressure uv preionised CO2 laser

Photoacoustic spectroscopy on gases with high pressure continuously tunable CO2 laser

“…The implementation of a high pressure C02 laser into a PA system is expected to provide a breakthrough in selectivity, since the overlapping of adjacent pressure-broadened transitions of the CO2 molecules results in a continuous tunability of the laser for pressures above ca. 10 bars [2]. We have developed such a high pressure C02 laser which we now use as radiation source in a novel PA detection system.…”
