Looks great. I take it JPT is a different type of laser than Raycus?

There are two types of JPT, LP and MOPA series. The special point of MOPA series is that the color can be marked on stainless steel. Compared with Raycus, JPT has a wider adjustable frequency range and is more expensive.

mopa laser has wider pulse eidth and frequency tunable range, can do color marking on SS copper silver ect., and mopa lasers are better in effect and efficiency
