1. Field of the Invention
The present invention generally concerns optical traps and tweezers for, and optical trapping and tweezing of, small and microscopic objects.
The present invention particularly concerns (i) a laser and laser arrays for optical traps and tweezers, (ii) the structure and operation of optical traps and tweezers based on the laser and laser arrays, and (iii) the properties of output light from this (these) laser(s) and laser arrays.
Referring particularly to the drawings for the purpose of illustration only and not to limit the scope of the invention in any way, these illustrations follow:
FIG. 1 is a prior art diagrammatic illustration of the gradient, and scattering, forces produced on a particle by incoming, and reflected/scattered (or diffracted/scattered) rays of light.
FIG. 2, consisting of FIGS. 2a through 2c, are prior art diagrammatic illustrations of, respectively, an up or a down or a left force pushing an object, illustrated as a microsphere, toward the focus of a light beam.
The following description is of the best mode presently contemplated for the carrying out of the invention. This description is made for the purpose of illustrating the general principles of the invention, and is not to be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
Although specific embodiments of the invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and are merely illustrative of but a small number of the many possible specific embodiments to which the principles of the invention may be applied. Various changes and modifications obvious to one skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention as further defined in the appended claims.
