With a goal for application to terahertz spectroscopy, we develop an optical trap with retroreflected CO2 laser beams that suspends microparticles of organic molecular crystals in a gas medium. Laser ablation with trapping radiation decomposes coarse-grained samples into micrometer-sized particles. We demonstrate that a consistent upward airflow partly cancels gravity and markedly improves the stability of optical levitation.
