Lasers Without Photons

Conference paper


The concept of lasers without inversion introduced some time ago by my colleague Steve Harris (1989) has not only added to his fame but spawned a world-wide industry, as evidenced by other papers in this volume. It seems appropriate, therefore, to consider the complementary concept of “lasers without photons”. Lasers without photons are of course easy to obtain: a laser which fails to operate is evidently a laser without photons. There can be a more serious interpretation of the phrase, however, and it is this interpretation that provides the title for this manuscript.
