Abstract
Embodiments include an apparatus including an optical fiber having a distal end with a distal surface configured to emit a beam of energy at an angle relative to a longitudinal axis of the optical fiber. The apparatus also includes a tube including a channel and a diffractive portion. The distal end of the optical fiber is disposed in the channel of the tube such that the beam of energy emitted from the optical fiber passes through the diffractive portion. The beam of energy emitted from the diffractive portion has a greater beam angle than the beam of energy directed to the diffractive portion.

An apparatus comprising:
- an optical fiber having a distal end with a distal surface configured to emit a beam of energy at an angle relative to a longitudinal axis of the optical fiber;
- and
- a tube including a channel and a diffractive portion, the distal end of the optical fiber being disposed in the channel of the tube such that the beam of energy emitted from the optical fiber passes through the diffractive portion,
- wherein the beam of energy emitted from the diffractive portion has a greater beam angle than the beam of energy directed to the diffractive portion.
A method of transmitting a beam of energy, the method comprising:
- transmitting a beam of energy through an optical fiber and toward a distal end of the optical fiber, the distal end of the optical fiber being disposed within a channel in a tube;
- emitting the beam of energy from the optical fiber at an angle relative to a longitudinal axis of the optical fiber;
- and
- transmitting the beam of energy through a diffractive portion to increase a beam angle of the beam of energy.
A laser assembly comprising:
- a laser source configured to produce a beam of energy;
- an optical fiber having a proximal end coupled to the laser source and a distal end, the distal end of the optical fiber having a distal surface configured to emit the beam of energy at an angle relative to a longitudinal axis of the optical fiber;
- and
- a tube including a channel and a diffractive portion, the distal end of the optical fiber being disposed in the channel of the tube such that the beam of energy emitted from the optical fiber passes through the diffractive portion of the tube,
- wherein the diffractive portion is configured to increase a beam angle of the beam of energy.
