Systems and methods for controlling laser transmission during ophthalmic procedures

A method for controlling laser transmission during an ophthalmic procedure, the method comprising:

• generating, by a first laser source, a first laser beam;
• generating, by a second laser source, a second laser beam;
• receiving, by an optical fiber, the first laser beam from the first laser source and the second laser beam from the second laser source;
• transmitting, by the optical fiber, the first laser beam and the second laser beam at a treatment area;
• receiving, at the optical fiber, a reflected portion of the second laser beam from an interface between the treatment area and the optical fiber;
• directing, by the optical fiber, the reflected portion of the second laser beam to a signal detector;
• receiving, at the signal detector, the reflected portion of the second laser beam from the optical fiber;
• and
• generating, by the signal detector, a signal detector output based on the reflected portion of the second laser beam, the signal detector output indicative of a presence or an absence of a bubble or vapor at a distal end of the optical fiber.
