Abstract
We report a GaInNAs/GaAs-based disk laser producing 7 W output power at 1180 nm wavelength at a temperature of 15 °C. The laser generated more than 5 W of output power when it was forced to operate with a narrow spectrum at 1178 nm. The gain mirror was grown using a molecular beam epitaxy reactor and it comprised 10 GaInNAs QWs and a 25.5- pair GaAs/AlAs distributed Bragg reflector.
