Re: Lasers (actually, just one...)

Jamie,
This appears to be part of a larger assembly. I have heard of devices like these used to measure movement over great distances. Perhaps in mining operations or seismic studies. It is obvious that the inner assy is sealed at both ends. Normally, one would look at the twist lock plug and assume that is for 120 v AC but frequently manufacturers would use this plug for 24 or 48 volt DC supplies. The twist lock prevents the power from being disturbed during vibration or movement. The parts visible in the slot with all the RTV on them is the high voltage section. Typical CO2 lasers use a supply of several thousand volts to initiate lasing. Although it may actually be the laser tube and hence the access through the side, I suspect that this hole may have been used for the addition of an accessory. You do not normally see a lens on the front of a laser which it appears this thing has. You would expect an optically flat window so this part is confusing.
