Abstract
Two-photon lasers have intrigued researchers for years because the dynamical behavior of this new class of highly nonlinear oscillator is very different from normal one-photon lasers. Experimental tests of the numerous, often conflicting, predictions regarding their behavior has been hindered by the lack of suitable gain media until the recent development of the dressed-atom two-photon gain medium. We observe ~30% two-photon optical amplification in a new type of laser-driven gain medium that is based on two-photon Raman scattering. This is ~300 times larger than previously reported dressed-atom gain.1 The enhancement is due to the relative insensitivity of the scattering process to broadening mechanisms allowing us to use a high-density atomic vapor.
