1. A laser probe comprising:

  • a handle having a handle distal end and a handle proximal end;

    a handle base of the handle having a plurality of handle base limbs wherein each handle base limb of the plurality of handle base limbs is at least partially disposed in a handle end cap;

    an actuation control guide of the handle having an actuation control guide distal end and an actuation control guide proximal end;

    a single flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end wherein the flexible housing tube proximal end is disposed in a flexible housing tube housing of the handle and wherein the flexible housing tube proximal end is fixed in the flexible housing tube housing;

    an actuation mechanism having an actuation mechanism distal end and an actuation mechanism proximal end wherein the actuation mechanism is disposed in an actuation mechanism guide of the handle;

    an inner bore of the actuation mechanism;

    an optic fiber housing of the actuation mechanism;

    an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the inner bore, the optic fiber housing, the actuation mechanism guide, and the flexible housing tube and wherein a portion of the optic fiber is fixed in the optic fiber housing;

    a polyimide buffer of the optic fiber configured to protect an optical property of the optic fiber; and

    an actuation control having an actuation control distal end and an actuation control proximal end wherein the actuation control is disposed in the actuation control guide and wherein an actuation of the actuation control within the actuation control guide towards the actuation control guide proximal end is configured to retract the optic fiber housing and the optic fiber relative to the flexible housing tube and curve the flexible housing tube.
