CDH-LOC lasers with lateral and transverse mode control in nonabsorbing mirror regions are realised by a single etch-and-regrowth cycle. The maximum achieved peak-pulsed output power (100 ns) and catastrophic-optical-damage (power-density) levels are 1.5 W and (20–30) MW/cm2, respectively. A linear power density of 200 mW/μm is reached at catastrophic damage. Fundamental-mode operation is obtained to 80 mW in narrow beams (θ∥≅7°; θ⟂≅15°).
