Laser engravers typically use either Nd YAG 1064nm lasers or CO2 10600nm lasers due to the high power levels required.

Due to the high power of these lasers typically an OD of 6 or greater is required.  More information on YAG lasers safety glasses suitable for 1064nm engraving lasers can be found via the below links.
