Welcome… My first question is, Why is the GF equipped with a sealed laser and not a water cooled?
It is water cooled. Just a sealed system inside the unit, with a very small internal reservoir, and circulating water pump.
edit: Not 100% water, but some liquid that hasn’t been revealed.

It is water(?) cooled, it’s just a closed self contained system. There is a heat exchanger that is cooled by the exhaust airflow. The exact nature of the coolant hasn’t been revealed.
One of the innovations that sets the 'forge apart. No separate bucket of water and pump to dance with, which makes it that much more portable and user friendly.
Because of that, the machine’s duty cycle is affected by the ambient temperature the laser operates in.

Funny that we typed the words “hasn’t been revealed” at the exact same time.

I was beaten too this while looking for @dan’s “haiku”.
Awww, the quote didn’t separate out the lines.

Glowforge is cooled by pure liquid magic!

@mr_jene55, thanks for asking. As noted, it is in fact liquid cooled. “Sealed” indicates that, unlike some lasers, you don’t need an external refrigeration unit (or bucket of ice water). It takes care of its own cooling.

The coolant is very likely something like this (which just happens to be BLUE 
)

This fact alone makes it worth the price of admission. And the wait.
