Coherent beam combining, paired with direct water cooling in the testing stage of development, has helped produce the new ultrafast fiber laser technology introduced by the Institute of Applied Physics (IAP) at Friedrich Schiller University Jena (University of Jena) and cooperating partners. Ph.D. student Michael Muller of the IAP presented the laser at this year’s OSA Laser Congress.
The laser delivered an average power that is approximately 10× that of current high-powered lasers, externally combining the output of 12 amplifiers. The combination enabled the laser to move beyond any issue caused by the waste heat that lasers generate when emitting light.
Fiber, slab, and thin-disk lasers feature distinct geometries…READ MORE
