SPI Lasers has released the R4 25-400W platform of air-cooled or water-cooled high powered fibre lasers.
Features include XPR (Extended Performance Range), PSE (Pulse Shape Equalisation), improved modulation performance and the choice of single-mode or multi-mode output beam configurations.
XPR and PSE build upon SPI's traditional performance in CW laser stability and modulation rate (CW to 100KHz). XPR allows a high power laser to be switched to operate at average powers down to less than one per cent of the maximum rated output power. The PSE feature overcomes the traditional laser problem of first pulse over or under-shoot ensuring the first pulse is as useable as the any other in the pulse train.
