Показано, что самопоглощение лазерного излучения 213 нм в тонком облаке испаренного материала сильно влияет на эффективность абляции. Продукты абляции выбрасываются в боковом направлении вдоль поверхности роговицы, в результате чего плотность энергии импульса на границе абляционной лунки Fbnd выше, чем пороговая плотность энергии Fth. Как следствие, радиус лунки rbnd меньше радиуса rth  лазерного луча, соответствующего пороговой плотности энергии импульса Fth, что необходимо учитывать при планировании абляционной хирургии глаза излучением 213 нм. </p></abstract><trans-abstract xml:lang="en"><p>The laser ablation efficiency of cornea at 213 nm radiation was investigated and optimized. It is shown that self-absorption of radiation at 213 nm in a thin cloud of ablated material takes place and strongly influences the ablation efficiency. Ablation products are being blown out in the lateral direction along the cornea surface, as a result of which the pulse fluence at the pit boundary Fbnd is more than the threshold fluence Fth. As a consequence, a pit radius rbnd is less than a laser beam radius rth corresponding to the threshold fluence Fth that should be taken into account in planning ablation surgery at 213 nm radiation. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>роговица глаза</kwd><kwd>лазерная абляция</kwd><kwd>213 нм</kwd><kwd>порог абляции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cornea</kwd><kwd>laser ablation</kwd><kwd>213 nm</kwd><kwd>ablation threshold</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Femtosecond-pulse laser ablation of human corneas/ W.
