Abstract
A method and device for using laser light to trap non-atomic particles optically within a hollow region of a hollow core optical fiber.
Claims16
The method of depositing a material onto a substrate, the method comprising:
- providing a solution containing the material;
- transforming at least a portion of the solution into a plurality of non-atomic droplets of the material near a first opening of an optical conductor having a through channel;
- confining the droplets inside a laser beam while directing the beam toward the first opening;
- transporting the droplets inside the through channel from the first opening to a second opening of the optical conductor by causing the laser beam with the confined droplets to propagate between the first and the second openings in the through channel;
- and
- depositing the droplets of the material onto the substrate after the laser beam exits the second opening of the optical conductor.

A method for depositing a material onto a substrate, the method comprising:
- providing one or more particles comprising providing one or more liquid droplets;
- confining one or more particles inside a laser beam while directing the beam toward a first opening;
- transporting one or more particles inside the through channel from the first opening to a second opening of the optical fiber by causing the laser beam with the confined one or more particles to propagate between the first and the second opening to a second opening of the optical fiber by causing the laser beam with the confined one or more particles to propagate between the first and the second openings in the through channel;
- treating one or more particles while transporting them inside the through channel, thereby providing the material for deposition;
- and
- depositing the material onto the substrate after the laser beam exits the second opening of the optical fiber.
3 more elements
A method of confining a particle inside a through channel of an optical fiber, the method comprising:
- directing a first laser beam into the channel through a first opening of the optical fiber,
- directing a second laser beam into the channel through a second opening of the optical fiber;
- and
- confining the particle inside the channel by causing the first and the second laser beams to propagate toward each other inside the channel.
1 more element
A method of confining a particle inside a hollow portion of a optical fiber, the method comprising:
- confining the particle inside a laser beam;
- directing the laser beam with the confined particle into the hollow portion through a first opening of the optical fiber;
- and
- transporting the particle inside the hollow portion by causing the laser beam to propagate inside the hollow portion until a velocity of the particle reduces to about zero.
