Laser treatment safety system

A method for laser treatment, comprising:

• monitoring a parameter at a source using a first sensor;
• generating first parameter data as a function of the parameter measured by the first sensor;
• monitoring the parameter at a treatment head using a second sensor;
• generating second parameter data as a function of the parameter measured by the second sensor;
• receiving the first parameter data and the second parameter data at a control system;
• determining whether the first parameter data or the second parameter data exceed a predetermined value;
• and
• modifying an operational parameter of the source using the control system in response to a determination that the first parameter data or the second parameter data exceed the predetermined value, wherein the predetermined value is a laser energy differential determined by calculating a difference between the first parameter data and the second parameter data at the control system.

A safety system for laser treatment, comprising:

• a source;
• a treatment head;
• a first sensor configured to monitor an energy per laser pulse parameter at the source and to generate first energy per laser pulse parameter data;
• a second sensor configured to monitor an energy per laser pulse parameter at the treatment head and to generate second energy per laser pulse parameter data;
• a control system configured to receive the first energy per laser pulse parameter data and the second energy per laser pulse parameter data and to determine whether the first parameter data or the second parameter data exceed a predetermined energy per laser pulse value;
• and
• the control system further configured to modify an operational parameter of the source in response to a determination that the first energy per laser pulse parameter data or the second energy per laser pulse parameter data exceed the predetermined energy per laser pulse value.
