Two-photon stimulated emission in laser-driven alkali-metal atoms using an orthogonal pump-probe geometry


Journal Article

We observe and analyze a two-photon continuous-wave optical gain mechanism designed for building a two-photon laser. The two-photon stimulated emission is spectrally isolated and resonantly enhanced using the multilevel structure of [Formula Presented] in conjunction with an alternative interaction geometry involving orthogonal beams and polarizations. The observed two-photon laser beam amplification increases linearly with low input laser beam intensity, as expected, and saturates at a gain of [Formula Presented] at high intensity. A theoretical analysis of the observations is outlined. © 1999 The American Physical Society.
