Fiber laser engravers commonly operate at 1064 nm Nd YAG laser wavelength. Typically they can be around 50W or greater in power and require laser safety glasses with a high OD level of protection such as an OD 6+ or OD 7+.
The LG-228 and LG-228N laser safety glasses shown in the below links protect against 1064 nm with an OD 7+ and have an L rating of LB7 which is required by US and International laser safety standards. They also provide also clear visibility.
