Abstract

We experimentally demonstrate a new technique for achieving efficient optical parametric amplification (OPA) which maintains the simplicity of conventional OPA implementation and works for common laser wavelengths using existing nonlinear media. This technique is achieved by simultaneously performing OPA and second harmonic generation at the idler wavelength. The dynamics of the two nonlinear processes hybridize, inhibiting back-conversion in the OPA and creating a long region of laser-like gain saturation. We show conversion of 2 μm picosecond pump pulses to 3.4 μm with 68% quantum efficiency, 44% internal pump to signal energy efficiency, and 48-dB gain in a bulk CSP crystal.
