我们提出了一种新的方案，光学冷却的粒子，原则上不需要一个封闭的光学过渡的理论分析。与被捕获的粒子相互作用的紧密限制的激光束经历相移，其在从镜子或谐振微结构反射时为粒子产生时间延迟的光学势。这导致非保守力和摩擦力。在半经典极限下，给出了系统的量子模型并进行了分析。
We present a theoretical analysis of a novel scheme for optical cooling of particles that does not in principle require a closed optical transition. A tightly confined laser beam interacting with a trapped particle experiences a phase shift, which upon reflection from a mirror or resonant microstructure produces a time-delayed optical potential for the particle. This leads to a nonconservative force and friction. A quantum model of the system is presented and analyzed in the semiclassical limit.
