Abstract
A two-chip OPS laser includes first and second OPS-chips each emitting the same fundamental wavelength in first and second resonators. The first and second resonators are interferometrically combined on a common path terminated by a common end-mirror. The interferometric combination provides for automatic wavelength-locking of the laser, which can eliminate the need for a separate wavelength selective device in the laser.
