Abstract
The frequency locking range of a laser diode array was experimentally determined. A one-dimensional array of seven lasers was phase-locked by placing it in an external optical cavity to establish coupling between the lasers. It was found that the experimental frequency locking range was four times greater than the theoretical locking range. The large experimental locking range demonstrates that there appears to be a greater tolerance of path-length errors in phase-locked laser arrays than the theory had earlier implied.
