QCW Single-mode Ytterbium Fiber Lasers

The Last Replacement Part you will EVER Need for your YAG Laser.

IPG’s new quasi continuous wave (QCW) fiber lasers are ideal for spot welding, seam welding & drilling in the long pulse operation mode. These air-cooled, compact units are substantially more cost-effective than conventional YAG lasers due partly to >30% wall-plug efficiencies and maintenance-free operation.

The QCW fiber lasers are available for requalifying existing lamp-pumped processes at IPG’s application facilities and applications labs. IPG's QCW Series also features a highly cost-effective OEM module. Retrofit services, including engineers familiar with system integration, are available to help customers replace older production lasers with energy-efficient fiber lasers from IPG.
