1. A method for adaptive control of optical pulses used to irradiate tissue, comprising:
- irradiating tissue with a sequence of optical pulses, the optical pulses directed in sequence to sites on the tissue;
during the irradiation sequence, making a measurement of a property of the tissue at a site already irradiated by one or more of the optical pulses; and
based on said measurement, adjusting a parameter of a subsequent optical pulse in the sequence according to an artificial intelligence algorithm.

Abstract
Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.
