The research, led by Professor Ravi Bhardwaj of uOttawa’s Department of Physics, demonstrates a new method for influencing ionization using optical vortex beams—light beams that carry orbital angular ...

The researchers also introduced a spiral phase plate to the 1,553-nm beam before frequency mixing, resulting in the generation of a vortex beam carrying orbital angular momentum. This marks the ...
