Abstract

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.

摘要

与目前在低温条件下使用纳米微机械谐振器来量化光辐射压力的努力不同，我们提出并通过实验证明了在环境条件下利用有效质量约为20克的宏观机械纵向振荡器进行辐射压力测量。附着在振荡器上的镜子上的光压力在迈克尔逊干涉仪中被记录下来，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良好。
