Abstract: An opening is formed in a cell using laser radiation. A Bessel beam is formed using the laser radiation and the Bessel beam is directed onto the cell to form an opening. The guiding of material towards the opening may be involved using optical trapping/manipulation. The material may change cellular function or analyse cell behaviour. Both pulsed laser radiation and continuous wave radiation may be formed using the same laser.

Abstract: A method of optimising at least one measure that is a quadratic function of a wavefunction, such as the spot size of a laser, the method comprising: superimposing a plurality of wavefunctions; determining a relationship between the superimposed wavefunctions and the quadratic measure, and using the determined relationship to identify the superimposed wavefunctions that provide a desired or optimised quadratic measure.
