High-power coherent beam combination of semiconductor laser arrays

We have coherently combined a total power of 7.2 W CW using an individually addressable 10-element-array of 980-nm slab-coupled optical waveguide lasers (SCOWLs). The robust, passive phase-locking is accomplished using a fractional Talbot external cavity.
