1. A light source comprising:

  • a light generator that generates a first light signal of a first wavelength and a first intensity that is set by a first control signal and a second light signal at a second wavelength and a second intensity that is set by a second control signal;

    a light monitor that generates a first monitor signal having an amplitude determined by said first intensity and a second monitor signal having an amplitude determined by said second intensity;

    a target signal generator having a port for receiving a target light signal, said target signal generator generating a first target signal having an amplitude indicative of a first target value and a second target signal having an amplitude indicative of a second target value from said target light signal;

    a feedback controller that generates said first and second control signals such that said first and second monitor signals have a fixed relationship to said first and second target signals, respectively.
