Abstract
A combined beam having a desired wavefront is produced from a first electromagnetic beam propagating in a beam direction and a second electromagnetic beam propagating in the beam direction and interfering with the first electromagnetic beam in an interference region. A first power measurement indicates a first combined power of the first electromagnetic beam and the second electromagnetic beam at a first sample point in the interference region. A second power measurement indicates a second combined power of the first electromagnetic beam and the second electromagnetic beam at a second sample point in the interference region. A phase difference between the first electromagnetic beam and the second electromagnetic beam is determined using the first power measurement and the second power measurement. The phase of the first beam can be changed based on the phase difference to produce the combined beam that has the desired wavefront.
