  text: Optical tweezers are widely used as a highly sensitive tool to measure forces
    on micron-scale particles. One such application is the measurement of the electric
    charge of a particle, which can be done with high precision in liquids, air, or
    vacuum. We experimentally investigate how the trapping laser itself can electrically
    charge such a particle, in our case a ∼1  μ⁢m SiO2 sphere in air. We model the
    charging mechanism as a two-photon process which reproduces the experimental data
    with high fidelity.
