Coherent beam combining of self-adaptive lasers

The novel technique of phase conjugate self-organised coherent beam combination is reported. It is demonstrated that due to the spectral mode freedom of a phase conjugate self-adaptive laser that efficient "all-passive" combination of many high quality lasers can be achieved. Efficient combination (>;92%) of two modules has been experimentally demonstrated to >;30W in continuous wave operation. Recent results demonstrating pulsed operation are also reported.
