Multiple other wavelengths are involved:

> Superfluorescent lasing occurs on cascaded 1327.3 nm (1st lasing) and 840.8 nm (2nd lasing) transitions.

> Subsequently, superfluorescent lasing occurs on cascaded 1409.4 nm (1st lasing) and 751.5 nm (2nd lasing) transitions.

... but these are infrared, so still no visible laser.

Anyone concerned about their eye health should be very worried about invisible lasers too. You won't notice you're cooking your eyeballs.

Owned night vision and an IR laser at one point.

Could you clarify how this relates to your first statement?

I would imagine that IR lasers come with large and scary warnings about the dangers of cooking anyone's eyes; and that night vision lets you see the unexpected paths that an IR laser can take, bouncing off reflective surfaces and such.
