the only way i no for sure is by using a night vision scope. most night scopes will pick up infared beams. I know ANPV-S 7D military grade nod will pick them up. i have used them myself.

If you have a digital thermometer you can use that. It should register a slight increase when the sensor is exposed to IR.

Fire it as a small piece of wood to see if it gets charred.

Infrared lasers are very dangerous. Be careful.
