Advancements in laser diode chip and packaging technologies for application in kW-class fiber laser pumping
Here we introduce an improved laser diode chip that has high reliability at higher output power. The single-emitter fiber-coupled platform now provides 12W. The multi-emitter platform has been refined for higher coupling efficiency, power, and brightness, and now supports up to 140W. Finally, Amada and JDSU have integrated these pumps into a fiber laser with high efficiency, enhanced reliability, and low beam parameter product (BPP) at 2.1, 4.2, and 6.3kW output powers.
