Abstract
The paper considers a number of principle algorithms to control feedback systems in submillisecond pulsed lasers designed for biological tissue treatment and having absorption coefficient within 0.1 cm-1 - 100cm-1. Feedback for those laser systems is based upon an analysis of amplitude and frequency characteristics of a thermo optical signal going along with a treatment of a tissue. Herewith some samples of thermo optical feedback algorithm realization for medical laser systems are presented. For the first time the paper demonstrates a must of a proportional change of laser radiation energy to a first variable of thermo optical signal amplitude signal amplitude in feedback systems at stabilized laser wound parameters.
