Abstract

A breakthrough in fiber laser technology has been achieved which opens the door to a whole class of efficient ultra-high brightness laser sources. These diode pumped devices have the potential to replace or augment almost all existing industrial, medical, and military laser applications. Kigre's new QX phosphate laser materials exhibit high strength, high gain, high durability and superior laser performance. This new laser glass material is well suited to suppliment the new fiber laser designs. Fiber lasers have now established themselves as leading contenders for a range of high-power applications. High efficiencies and high gain are readily achieved, and the problems of themal loading and beam distortion can essentially be eliminated.
