Nm range of “china” green laser pointer converted to IR?

I've got a 5mw Chinese laser pointer that I removed the pumping crystal from to make it into an IR pointer.

I’m going to get a 1mw green laser and convert it, so it’s a bit safer than my 5mw one.

I want to wear laser goggles, but I need to know the Nm of the laser, so I can buy the right goggles.
the laser pointer I'd be converting would be 532nm in it's green form.

Thanks for any info.
