Abstract
A first optical fiber (12) having a first end and a second end is connected to a multimode second optical fiber (14) at the second end. The first optical fiber (12) outputs a substantially single mode optical beam at its second end. The multimode second optical fiber (14) converts light in the optical beam of single mode from the first optical fiber to light of multiple modes, and provides an output beam that has less diffractive spreading than that of a Gaussian beam.
Claims18
An apparatus for generating optical beams comprising:
- a first optical fiber having a first end and a second end, said first optical fiber outputting a substantially single mode optical beam at its second end;
- and
- a multimode second optical fiber connected to said second end of the first optical fiber to convert light in the optical beam of said single mode from said first optical fiber to light of multiple modes, and to provide an output beam that has less diffractive spreading than that of a Gaussian beam.
A method for generating optical beams comprising:
- providing a structure comprising a first optical fiber having a first end and a second end spliced to a multimode second optical fiber at said second end;
- and
- supplying a light beam to the first end of the first optical fiber so that said first optical fiber output a substantially single mode optical beam at its second end to the multimode second optical fiber, wherein the single mode optical beam is converted to light of multiple modes, the multimode second optical fiber thereby providing an output beam that has less diffractive spreading than that of a Gaussian beam.
