Can you buy a laser first and add extraction later?
Our position, and the phased-purchase counterpoint.
Our position
If your total budget is $1,200 and a laser costs $1,200, you cannot afford that laser. You need to set aside $250-1,300 for fume extraction on top of the machine cost. A laser without extraction is a machine you cannot safely turn on. Cut the machine budget to leave room, or wait until the full budget is available.

Laser vendor bundle pricing
Broadly agreesThe major school-targeted laser vendors increasingly sell machine-plus-extraction bundles, priced with the extraction integrated. The industry knows the extraction is not optional.
Fire marshal / insurance guidance
Broadly agreesSchool fire marshals and insurance policies routinely require extraction for cutting lasers. You cannot get the permission to turn it on without it.
Phase-purchase-but-don't-run advocates
Pushes backSome teachers buy the laser, keep it boxed, and fundraise for extraction separately. Fine, as long as the laser stays off until extraction arrives.
