760 nm: Jenoptik's new color for aesthetic applications

Abstract

The performance of new Jenoptik 760nm laser bars for aesthetic applications is presented. We have developed and industrialized laser structure utilizing Al-free active region embedded in $\text{Al}_{\mathrm{x}}\text{Ga}_{1-\mathrm{x}}\text{As}$ wave-guiding material. We demonstrate laser operation of 760nm-bars in 1kW multicolor laser-stack as well as long-lifetime tests results.
