We demonstrate a broad area (400 μ m) high power quantum cascade laser (QCL). A total peak power of 62 W operating at room temperature is achieved at λ ~4.7 μ m. The temperature dependence of the peak power characteristic is given in the experiment, and also the temperature of the active zone is simulated by a finite-element-method (FEM). We find that the interface roughness of the active core has a great effect on the temperature of the active zone and can be enormously improved using the solid source molecular beam epitaxy (MBE) growth system.
