在周围环境中使用宏观振荡器测量辐射压力

Radiation pressure measurement using a macroscopic oscillator in an ambient environment

Mikko Partanen, Hyeonwoo Lee, Kyunghwan Oh

摘要:

在目前的努力,以量化的辐射压力的光使用纳米微机械谐振器在低温条件下,我们提出并实验证明了在环境条件下的辐射压力测量,通过利用宏观机械纵向振荡器的有效质量的顺序为20克。在迈克耳孙干涉仪中记录了作用在振子上的反射镜上的光压力,结果表明,在3.9%的实验精度范围内,与无自由参数的谐振子模型吻合得很好。

英文摘要:

In contrast to current efforts to quantify the radiation pressure of light using nano-micromechanical resonators in cryogenic conditions, we proposed and experimentally demonstrated the radiation pressure measurement in ambient conditions by utilizing a macroscopic mechanical longitudinal oscillator with an effective mass of the order of 20 g. The light pressure on a mirror attached to the oscillator was recorded in a Michelson interferometer and results showed, within the experimental accuracy of 3.9%, a good agreement with the harmonic oscillator model without free parameters.
