SUMMARY
The discussion centers on identifying gases that effectively absorb Nd:YAG laser radiation at 1064 nm for heating purposes. Water vapor is highlighted as a potential candidate, although it is noted that it does not absorb as much IR radiation at this wavelength compared to other options. The current method involves using a superheated nitrogen torch, which has been tested alongside various absorbents. The consensus is that while water vapor is not ideal, it remains one of the better atmospheric gas options available.
