You won't see IR, near IR looks like a faint red.

If it's green it's not IR ;D But if you meant, a way to look if your green also outputs IR you can look with a webcam without IR filter. Greens without filters usually output 808nm and 1064nm which you won't see with a naked eye, but you can see on a webcam without ir filter, making the green laser go through a pair of 532nm lasershades will help seeing the IR with the webcam because the shades will only let the IR go through and some green.

Sorry but you can't tell by a picture if it has IR in it.
