▲ [20p-211B-2] Simple Techonolgy to Freely Manipulating Nonlinear Optical Frequency Conversion Processes
Keywords:optical frequency conversion, phase manipulation, four-wave-mixing
We firstly applied the technology to a Raman-resonant four-wave-mixing process in parahydrogen gas medium experimentally. Coherence established by using two incident electricmagnetic fields(ω0,ω-1) coherently exciting parahydrogen molecules. The coherent molecules modulate an additional incident field(ωT0) to generate its discrete equidistant radiations(ωT±1, ωT±2, …). Due to manipulating their phase ralationships, the energy of additional incident field(ωT0) could be gathered at its first Stokes ωT-1 or its first anti-Stokes ωT1 at will.
Manipulating among higher order Stokers or anti-Stokes is also feasible. With this technology, it's expected that tunable single frequency pulsed laser throughout the vacuum-ultraviolet range could be generated in future.
