Abstract
Conventional master oscillator power amplifier (MOPA) devices have experienced poor beam quality due to edge effects. The lateral current tailoring described herein was one attempt at improving the laser beam quality. Experimental results have indicated that this approach can make improvement in beam quality, using nonlinear leading edges in the gain stripe of MOPA amplifiers.
