“…Two optical traps were formed with total laser power of 2.5 W and a strength (the percentage of the total laser power which contributes to the trap) of 100%. The positions of the laser beams (and therefore the traps) were controlled using an acousto-optic deflector (AOD) …”

“…The positions of the laser beams (and therefore the traps) were controlled using an acousto-optic deflector (AOD). 45 In the experiments, the two traps were formed at an initial distance of 21 μm. One of the traps was then sequentially displaced by the laser beam along a straight line connecting the centers of the particles at a constant velocity.…”

Combined laser variosystems paraxial design for longitudinal movement of a Gaussian beam waist

2020

View full text Add to dashboard Cite

Optical variosystems that form the required diameter of the Gaussian beam waist and perform its smooth longitudinal movement with a constant diameter for laser technologies, processing materials, moving microobjects, etc., are considered. A combined method based on a movable tunable-focus lens for changing the optical characteristics of laser variosystems is proposed. The features and fundamental differences between the laws of transformation of Gaussian beams by optical systems of different structures for the dimensional synthesis of laser variosystems are discussed. Based on these laws and the theory of laser optics, a method for the dimensional synthesis of one- and two-component laser variosystems is developed, an algorithm for their automated synthesis, and an example of calculation are given.
