Lasers are the tool of choice no matter what the material as they produce permanent marks with a non-contact process at high speed with high precision. Laser marking requires no consumables and marks are computer generated and are therefore highly flexible.

Innovative Technology

PulseTune technology offers the OEM integrator highly flexible control over pulse width and peak power. The unique PulseTune function enables market leading repetition rates whilst maintaining peak power threshold.


The key differentiator of SPI's redENERGY pulsed lasers is the versatility of the 25 selectable waveforms and the benefits that accompany its flexibility. The ability to optimize key pulse characteristics to individual applications gives enhanced process quality and productivity.

No Maintenance

Every care has been taken at the design stage to ensure that our products offer a long and maintenance free life. It is an easy-to-integrate DC-powered OEM fiber laser module with integral controller designed to interface with common laser-marking equipment.

Multiple Applications

SPI's redENERGY pulsed lasers achieve excellent results in marking and micro-machining, they suitable for a very wide range of high precision micro-machining applications and out-perform conventional lasers in many types of marking applications.
