The paper presents the results of fast detection of the keyhole formation in titanium under point exposure to laser radiation. The fact has been established that the keyhole evolution ends with a collapse even before the cessation of the action (switching off) of the continuous laser radiation. Keywords: deep penetration, keyhole, collapse, laser radiation.
