First realization of new ps-10 micron-CO2-OFID laser systems with far-infrared laser gases as spectral filters

The first operation of a ps 10-micron CO2 laser system using optical free induction decay (OFID) in far-infrared laser gases (CH3F, D2O, and NH3) is demonstrated. It is noted that these laser systems promise advantages over the standard CO2-laser OFID systems based on a hot CO2 cell because they ope...

Description
Summary:The first operation of a ps 10-micron CO2 laser system using optical free induction decay (OFID) in far-infrared laser gases (CH3F, D2O, and NH3) is demonstrated. It is noted that these laser systems promise advantages over the standard CO2-laser OFID systems based on a hot CO2 cell because they operate at significantly lower gas pressure and temperature (1.4 torr CH3F at 300 K instead of 300 torr CO2 at 650 K). An important advantage of the OFID 10-micron CO2 laser systems is considered to be the fact that they work only at selected CO2 laser lines in contrast to the standard OFID CO2 laser systems equipped with a hot CO2 gas cell.
