Pointers are usually 1-5mW, maybe 10mW at the extreme.
1W is serious, especially at green where the eye's response is most sensitive.
I've no idea what a legitimate use of such a device would be: lamping rabbits in the next county?
For $300 the frequency stability will surely be all over the place, leaving plenty of fingerprints for the police helicopters' fancy new forensic laser spectrograph thingy, (
BBC NEWS | UK | New weapon targets laser attackers). (Unless it gets burned out by the laser pointer.) Hopefully, the focus will be rotten too, getting less energy per eye in the sky.
