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.
Very insightful. Some details:

The "lens" (as I called it) appears flat on the exterior side, and does not seem to bend light like a true lens.

There is something backing the larger assembly theory. there is a substance on the front and back end of it similar to fun foam. It appears scraped or peeled at, and it seems that it originally covered the 6 screws on the front.

It fits loosely within the "sleeve". (ie, 1/4" or so difference in size.) There are 4 screw holes at the power end of both the black assembly and silver tube, making me think they were originally attatched with something in between. There is also a single groove long-ways in the outside of the sleeve, and a "ditch" ring on the focal end of the sleeve (ie, opposite the screw holes).
