Abstract

We report on recent progress in the generation of non-diffracting (Bessel) beams from semiconductor light sources including both edge-emitting and surface-emitting semiconductor lasers as well as light-emitting diodes (LEDs). Bessel beams at the power level of Watts with central lobe diameters of a few to tens of micrometers were achieved from compact and highly efficient lasers. The practicality of reducing the central lobe size of the Bessel beam generated with high-power broad-stripe semiconductor lasers and LEDs to a level unachievable by means of traditional focusing has been demonstrated. We also discuss an approach to exceed the limit of power density for the focusing of radiation with high beam propagation parameter M². Finally, we consider the potential of the semiconductor lasers for applications in optical trapping/tweezing and the perspectives to replace their gas and solid-state laser counterparts for a range of implementations in optical manipulation towards lab-on-chip configurations.

来自半导体光源的贝塞尔光束

我们报告了从半导体光源产生非衍射(贝塞尔)光束的最新进展，包括边缘发射和表面发射半导体激光器以及发光二极管(led)。贝塞尔光束的功率水平为瓦特，中心瓣直径为几到几十微米，这是由紧凑和高效的激光器实现的。将大功率宽条纹半导体激光器和led产生的贝塞尔光束的中心瓣减小到传统聚焦方法无法达到的水平的可行性得到了证明。本文还讨论了在高光束传播参数M2条件下，实现辐射聚焦超过功率密度限制的方法。最后，我们考虑了半导体激光器在光捕获/光镊中应用的潜力，以及取代气体和固态激光器的前景，以实现对芯片实验室配置的一系列光学操作。
