ABSTRACT:
A method of producing coherent mode radiation comprises passing direct currents through a pair of injection lasers optically coupled together but controllable separately, one laser of good optical quality (O-factor) and spectral purity being excited above its threshold and the other laser having a lower optical quality and having a modulated current superimposed on its dc current. An arrangement suitable for carrying out such a method is also provided.
