PUMP RECYCLING SCHEME FOR TERAHERTZ GENERATION |
摘要 |
<p>Structures and techniques are disclosed that enable efficient generation of terahertz (THz) radiation capable of surpassing the fundamental quantum limit, as defined by the Manley-Rowe relations. In one particular embodiment, a difference frequency mixing (DFM) crystal stage receives pump radiation and signal radiation, and generates THz radiation. Leftover signal radiation from the DFM stage is then used to pump an optical parametric oscillator (OPO) stage, which is used to generate another mixing signal and more THz radiation. The output signal and the residual pump from the OPO stage can then be used in a subsequent DFM process to generate even more terahertz radiation, and further drives a subsequent OPO stage. Such cascaded OPO, DFM, OPO staging can be repeated to maximize total amount of THz output power.</p> |
