We report on the successful demonstration of nonabsorbing mirrors in Al-free broad area lasers with reliable operation at 2W and a 70C heatsink temperature. We have used a quantum-well intermixing technique to create nonabsorbing mirrors (NAM) in Al-free broad area lasers. We have life-tested these devices at 2W and a 70C heat sink temperature with virtually no degradation over 2000 hours.
