Abstract
Continued advances in high power diode laser technology enable new applications and enhance existing ones. Recently, mini-bar based modules have been demonstrated which combine the advantages of independent emitter failures previously shown in single-stripe architectures with the improved brightness retention enabled by multi-stripe architectures. In this work we highlight advances in a family of compact, environmentally rugged mini-bar based fiber coupled Orion modules. Advances in PCE (power conversion efficiency) and reliable operating power from a 9xx nm wavelength unit are shown from such modules. Additionally, highly reliable fiber coupled operation and performance data is demonstrated in other wavelengths in the 780 - 980 nm range. Data demonstrating the scaling this technology to 25W and higher power levels will be given.
