YVO4 Laser Series


Our DPSS (Diode-pumped solid state) Lasers utilize Nd:YV04 technologies, creating many advantages over other lasers. They can produce a precise mark without using large, external power supplies, which is energy-efficient. YV04 lasers can achieve a smaller spot size and higher energy density,  which is ideal for reflective surfaces. RMI Laser’s YV04 Laser Series comes with the world’s most compact marking head for easy integration into a variety of process flows and configurations, and an industry leading 3-year warranty and loaner program.

They are by far our most versatile laser marker machines because they can anneal metals, ablate coated metals, and color change or foam plastics all with a single laser system. If versatility is what you need, then this is the laser system for you.

The YV04 Laser Series Systems have a very short pulse duration, making them ideal for sensitive marking applications where direct part marking can cause surface degradation. Users can mark directly onto the parts without concern for surface damage, HAZ (heat-affected zones), structural degradation, recasting or stress risers.

The newest systems in the RMI Laser YV04 Laser Series are the A-10 and A-20. Expanding upon the technology and components from the current U-Series, the A-10 and A-20 have added application capabilities. The beam is specifically tuned to uniformly distribute energy making it optimal for annealing and ablating. This laser is strong enough to create dark marks on metals and is sensitive enough to get a color change on plastics without any foaming. The new laser systems have higher power and more stability than its predecessors along with having unmatched marking quality.
