Unlocking quantum potential with widely tunable OPO lasers: from frequency conversion to atomic transitions in hard-to-reach infrared

Siamak Dadras, Andrew Ross, Pei-Wen Tsai +2 more

Widely tunable optical parametric oscillator (OPO) lasers have recently shown great potential in quantum applications. Their ability to generate low noise, Watt-level optical power and access arbitrary wavelengths in the near-IR and mid-IR makes them ideal for nonlinear frequency conversion of non-telecom photons from atomic or solid-state systems into telecom photons, enabling photonic interconnects in quantum computing, sensing, and communication. Additionally, OPOs have been used for inducing high-Rabi-frequency optical excitations, such as in Rydberg sensing, by providing low-noise, high-power coherent light at hard-to-reach wavelengths. This presentation highlights the design of two OPO systems by TOPTICA Photonics, focusing on their quantum applications, including photon frequency conversion and atomic transitions at exotic wavelengths in the near-IR and mid-IR.Widely tunable optical parametric oscillator (OPO) lasers have recently shown great potential in quantum applications.

Summarization of Investigation in Mechanism of Spontaneous Parametric Down-Conversion and Its Applications

Jianjun Li

Spontaneous parametric down-conversion is a non-classical optical field,which is generated by the interaction on nonlinear crystal of monochromatic flux of pumping photons and quantum vacuum noise.In this paper,the generation mechanism of spdc light field is interpreted by theory of quantum mechanics;the interpretation by classical theory is also given here.The paper also introduces roundly the non-classical characteristics and application advances of spdc light field in laser,remote sensing and quantum communication.Last but not least,SPDC′s application prospect and its developing direction are also given in this paper.Spontaneous parametric down-conversion is a non-classical optical field,which is generated by the interaction on nonlinear crystal of monochromatic flux of pumping photons and quantum vacuum noise.In this paper,the generation mechanism of spdc light field is interpreted by theory of quantum mechanics;the interpretation by classical theory is also given here.The paper also introduces roundly the non-classical characteristics and application advances of spdc light field in laser,remote sensing and quantum communication.Last but not least,SPDC′s application prospect and its developing direction are also given in this paper.
