A new approach for stable intra-cavity phase locking of several laser channels is presented. In this approach, special interferometric couplers are incorporated inside a laser resonator to obtain efficient self phase-locking between separate laser channels. We analyze the approach and demonstrate experimentally phase-locking of two and of four laser channels, that are derived from Nd:YAG lasers, with 92% and 83% power efficiencies respectively.
