Systems for real-time laser power monitoring

A method comprising:

• generating, by a first laser source, a first laser beam in a pulsed form;
• generating, by a second laser source, a second laser beam;
• receiving, by an optical fiber, the first laser beam from the first laser source;
• directing, by the optical fiber, the first laser beam to patient tissue to form a bubble in the patient tissue;
• receiving, at the optical fiber, the second laser beam from the second laser source;
• directing, by the optical fiber, the second laser beam to the patient tissue;
• receiving, at the optical fiber, a reflected portion of the second laser beam from an interface of the patient tissue and the optical fiber;
• directing, by the optical fiber, the reflected portion of the second laser beam to an optical detector;
• receiving, at the optical detector, the reflected portion of the second laser beam from the optical fiber;
• determining, by a controller in communication with the optical detector, one or more widths of one or more pulses in an output of the output of the optical detector;
• and
• determining, by the controller, an estimated energy for one or more pulses in the first laser beam based on the one or more widths.
