    We developed a compact, affordable near-infrared optical trapping system using laser diodes and a simple lens. This setup is easily integrated into microscopes for versatile light manipulation applications.

    Area of Science:

    • Optics and Photonics
    • Biophysics
    • Microscopy

    Background:

    • Optical trapping utilizes focused laser beams to manipulate microscopic particles.
    • Traditional optical trapping systems often require complex and expensive laser sources.
    • Developing cost-effective and compact near-infrared light sources is crucial for broader accessibility.

    Purpose of the Study:

    • To design and implement a novel optical-trapping configuration.
    • To utilize near-infrared laser diodes for optical trapping applications.
    • To investigate the impact of a non-Gaussian beam profile on trapping forces.

    Main Methods:

    • Collimation of highly divergent diode laser output using a single aspheric compact disc lens.
    • Characterization of the resulting astigmatic and elliptic beams with a flat intensity profile.
