Laser Engraving advise:

Copper and Niobium offers a unique combination for laser engraving.

Copper needs alot of power and a low frequency setting, while niobium engraves similar to titanium and becomes rough with low freq and high power. I have found a high freq and medium power setting can engrave the niobium cleanly while at the same time leave the copper almost intact. This provides a unique circumstance where the niobium can be engraved to a deeper depth than the copper.
