Welcome to the Forum :wave:
Where did you buy the laser from?

You say its was tested at 160mW, is it just an estimation or you have a lcalibred LPM?

If you used a lpm, did u try to put an ir filter at the exit of the beam before measurements?

Impossible. Please take detailed pictures of the laser, Laser power meter and your IR filter.

Also, a link to the site where you purchased would be great, or if not, simply the price payed will give as at least some info.
