Abstract:
The spectral and spatial behavior of monolithically integrated distributed-feedback tapered master-oscillator power amplifiers emitting around 973 nm is experimentally and theoretically investigated.We demonstrate a good agreement between experiments and theory and analyze peculiarities of the observed dynamical regimes.
