SPI Lasers’ redPOWER® QUBE series of CW fiber lasers is efficient and flexible and provides exceptional levels of power and control while cutting, welding, and drilling.

Depending upon customer requirements, redPOWER® QUBE lasers can be supplied with a variety of power outputs from 300 W all the way up to 10 kW. There are four models in the redPOWER® QUBE CW fiber lasers range, designed to have the flexibility to meet all your laser power requirements.

All redPOWER® QUBE CW fiber lasers are designed to be maintenance-free, utilising ‘Fit & Forget’ technology, allowing you to focus on output, rather than time consuming maintenance schedules. Designed for manufacturability and reliability, the redPOWER® QUBE series sets new standards of product quality, backed by comprehensive warranties as standard.

SPI Lasers’ redPOWER® QUBE air-cooled fiber laser range, covering 100 W to 500 W, offers a number of industry leading features in a standard 19“ rack format, with an integrated power supply making it simple to integrate and install into the customer’s new or existing systems where the added complexity of providing water cooling is undesirable.

The redPOWER® QUBE water-cooled fiber laser range, covering 300 W to 2000 W, offers easy integration into the customer’s equipment. These versatile industrial lasers come complete with their own internal control system and offer a number of benefits including output power flexibility and a range of beam delivery, control and interface options.

SPI Lasers’ redPOWER® QUBE Multi-kW water-cooled fiber laser range, covering 3 kW to 10 kW,
provides exceptional levels of continuous, reliable power and control for high-throughput industrial laser manufacturing applications. The complete integrated systems require only an electrical and chilled water supply to deliver kWs of laser power into 50 to 300 μm fiber outputs up to 20 m in length.

In addition to the redPOWER® QUBE series, SPI Lasers also provides a dedicated series of redPOWER® PRISM OEM CW fiber lasers that allows integrators to manufacture equipment for cutting, welding and other material processing applications in the industrial/manufacturing sector while maintaining their own brand throughout. For applications requiring high pulse energies, please refer to SPI Lasers’ redENERGY G4 series of high-energy pulsed fiber lasers, providing maximum pulse energies of up to 5 mJ and peak powers of up to 50 kW.
