About RMI

RMI Laser Capabilitie

Desktop Laser Marking • Automated Laser Marking • DPSS Laser Systems/Sources •  Designed • Manufactured • Tested & Supported 


RMI-Laser-Staff-Group-PhotoFounded in 1998, RMI Laser, LLC was the first to commercialize the highly efficient Nd:YVO4 technology. We have over thousands of system sold in over a dozen countries for last 12+ years.  

Our product spectrums include Nd:YVO4, Nd:YAG, and latest fiber laser. The newest UF-20 fiber laser marking system is the culmination of years of development based upon our previous technologies and experiences. So you can easily select the optimal laser marker for your application from our broad product range; UM-1, U-10, U-15, UF-20, U-5G, etc.


RMI Laser has various models of 1064nm and 532nm laser marking systems as well as laser source/platform products in our laser product line. U, UF, and UM series laser markers (U-10, U-15, U-5G, UF-20, and UM-1, etc) are current flagship model line-up. The UM-1 is the reasonable price precision laser marker which was officially release on July 2008 and priced less than US$20,000. We will introduce more powerful YVO4 based new model (U-20) laser marking system very soon.


We are the first commercial YVO4 laser marking system manufacturer in the world.  The YVO4 has lots of benefits rather than other technologies

Our laser marking systems can be applied to any industries which need marking/engraving. Major customers are in hardware (such as tool, automobile, etc), military, semiconductor, medical industries, jewelry, and so on, but there is no limit to apply our marking system. Laser marking is a non-contact and permanent marking/engraving method on metal, plastic, glass, rubber, jewelry, and so on. Photograph marking is also one of our laser marking systems' famous and powerful features.
