Method for stabilizing delivered laser energy
First Claim
1. A method for stabilizing an amount of laser energy delivered to a target by a laser generating device of a laser eye treatment system, the method comprising:
- measuring the amount of delivered laser energy arriving at or near a target from the laser generating device of the laser eye treatment system over a period of time;
calculating a decrease in the amount of delivered energy over time caused by passage of the laser energy along a delivery path, which causes an accumulation of at least one substance along the delivery path, the substance impeding subsequent passage of the laser energy; and
adjusting the laser generating device to compensate for the decrease to stabilize the amount of delivered laser energy arriving at the target by increasing an amount of laser energy provided from the laser generating device over the time to compensate for the accumulation of the at least one substance along the delivery path.

Abstract
Systems and methods provide for stabilizing the amount of laser energy delivered to a target from a laser device. Generally, delivered laser energy is measured over multiple laser pulses or over time in the case of a constant wave laser. A decrease is then calculated in the delivered energy, the decrease being caused by accumulation of one or more substances, such as ozone, along the laser beam delivery path due to passage of the laser beam along the path. Using this calculated decrease, a laser device may be adjusted to compensate for the decrease in delivered energy due to the accumulated substance(s), thus stabilizing the amount of energy delivered to the target.
