Paper Abstract

Advanced high volume applications require pumps with high power, high brightness, and high power efficiency. New generation devices meet all of these challenging requirements, while still maintaining the advantages of distributed pumping architecture including high reliability inherent to single emitter sources. Based on new-generation long-cavity diode chips, new pumps are capable of more than 60W CW power ex-fiber output (100 μm core diameter) into NA ~ 0.12. Peak power efficiency stays over 60%. All of the above is provided at room heatsink temperature, maintained by basic air- or water-cooling.
