SPI buffs up its lasers

Share this on social media:

SPI Lasers has increased its air-cooled lasers from 100 to 200W power and water cooled from 200 to 400W power, while also creating unique laser control functions offering direct application benefits across a wide range of laser machining applications.

New features on the R4 laser platform include XPR (Extended Performance Range) and PSE (Pulse Shape Equalisation). These new features build upon SPI’s traditional performance in CW laser stability and superior modulation rate (CW to 100KHz). XPR allows a high power laser to be switched to operate at average powers down to < one per cent of the maximum rated output power. The PSE feature overcomes the traditional laser problem of first pulse over or under-shoot.
