1. A tunable laser source apparatus enabling a laser diode to be pumped to lase in an extra-cavity environment having no external reflectors and thus consisting essentially of:

  • (a) an optical phase modulator optically coupled to said laser diode; and

    (b) tuning control means for shifting the phase of a light wave modulated by the optical phase modulator such that a resonant frequency of said light wave is shifted.
