We report an experimental demonstration of dual-channel all-optical wavelength conversion switching in hot Rb vapor. In a four-level atomic system, a coupling field and a pump field interact with both (87)Rb and (85)Rb isotopes simultaneously and facilitate the generation of two nonlinear signals when the probe field is applied to the corresponding transition. Each nonlinear signal is switched on and off separately by the pump field at different frequencies based on four-wave mixing and isotope shifts.
我们报道了在热铷蒸汽中双通道全光波长转换开关的实验演示。在一个四能级原子系统中，一个耦合场和一个泵浦场同时与⁸⁷Rb和⁸⁵Rb同位素相互作用，并在将探测场应用于相应跃迁时促进产生两个非线性信号。基于四波混频和同位素频移，每个非线性信号通过不同频率的泵浦场分别进行开关控制。
