Hello all and thanks to all that helped me with my initial question on laser Fiber Laser purchase. I chose to buy direct from RayFine and purchased a 30W MOPA with autofocus and Cyclops system. I ordered it with a custom enclosure for eye protection and I think it will be easier to make an exhaust system should it become necessary. The laser has been complete for a week now but the holdup is the cover is not yet done so I wait. Hopefully it will ship next week and will arrive quickly.
My purpose for this thread is the machining company that I sold asked me to mark some gold plated stainless plates. A very simple job but after reading some archived posts my concern is that beam reflection could harm the machine. Rayfine said it was able to mark gold and that the lens offers protection but they said that off center marking would be best. What do they mean by off center marking? Does that mean to tilt the plates so that the beam would bounce away instead of straight back. Anybody routinely mark gold plated stainless with a fibre that would care to share results?
