Optical trapping of spermatozoa using Laguerre-Gaussian laser modes

Raktim Dasgupta, Sunita Ahlawat, Ravi Shanker Verma, Sunita Shukla, and Pradeep Kumar Gupta

We report results of a study on the use of Laguerre-Gaussian (LG) modes for optical trapping of spermatozoa. The results show that for a given trap beam power the first-order LG mode (LG01) leads to lower photodamage to the cells without compromising the trapping efficiency.
