Diode lasers are key sources of optical energy for industrial machine tools and continuous improvement in their performance is needed to support performance and cost scaling efforts. For example, disk lasers as used in laser tools for metal cutting a

High-Power Diode Laser Technology XVIII.
We present 1 kW-emitting diode-laser bars optimized for higher conversion efficiency and smaller far-field angle Θ95% power content), as needed, e.g., for solid-state laser pumping (wavelength λ= 940 nm). First, we review the latest high-efficiency

We report the first demonstration of 1.2 J-emission into long pulses ( $\ge 2$ ms) from passively cooled laser bars. These efficient high-fill-factor bars were developed for long-pulse pumping of Yb:CaF2-laser media at a power level of 600 W. The spa

High power, efficient diode-laser bars with narrow far field angles are sought for many applications, for example in the 9xx nm-range for the pumping of Yb:YAG disc and slab lasers [1,2]. In previous work, broad-area (BA) diode-laser bars with 4 mm r

High-Power Diode Laser Technology XVI.
Progress is presented on ongoing research and development into ultra-high power and efficiency bars that achieve significantly higher useful optical output power and higher brightness than are currently commercially available. In previous work (2017)

High power diode lasers in the 9xx nm wavelength range are required for application in material processing, such as metal cutting and welding, either directly or as pump sources for solid state or fiber lasers. For example, continuous wave (CW) 1-cm
