We observe coherent, cw, 455 nm blue-beam production via frequency upconversion in cesium vapor. Two IR lasers induce strong double excitation in a heated cesium vapor cell, allowing the atoms to undergo a double cascade and produce a coherent, collimated, blue beam copropagating with the two IR pump lasers.

  19. The steady-state solution to a four-level OBE model shows that the coherence between the 6S1/2 and 6D5/2 states is nonzero. The off-diagonal density matrix element ρ13 is proportional to the coherence and does not decay to zero in the steady state.
  20. We assumed a Rabi frequency of 1 MHz for both the 455 nm and 15.1 μm beams. The transition probabilities used for the 6S3/2-->6P1/2, 6D5/2-->6P3/2, 6D5/2-->7P3/2, and 7P3/2-->6S1/2 transitions were 5, 15.2, 0.063, and 0.795 MHz, respectively. Branching ratios can be found in [15].
