1. An optical apparatus comprising:

  • a) a combiner having a combiner output port and having N≧

    2 input ports indexed with an integer i;

    b) a set of N optical radiation sources in one to one correspondence with said input ports, each of said sources providing input optical radiation having an input power Pi to said corresponding input port; and

    c) an optical frequency converter optically coupled to said combiner output port and providing output optical radiation;

    wherein at least one of said sources receives source feedback optical radiation having a non-zero feedback power Fi from said frequency converter,wherein said source feedback optical radiation is optically coupled to said at least one of said sources to provide optical feedback,wherein said feedback power Fi has a nonlinear dependence on the corresponding input power Pi.
