Summary, in English

Singly, doubly, triply, and quadruply charged krypton ions are formed by multiphoton absorption processes in krypton atoms. They are induced by a 50-psec laser pulse at 1.064 m in the 1013-1014-W-cm-2 intensity range. The percentage ratio between the numbers of doubly and singly ionized Kr atoms is 10% at 8×1013 W cm-2. It is shown that Kr2+ ions result from a direct 33-photon absorption process. At 1.5×1013 W cm-2, the 33-photon absorption rate is only about 60 times less than the 13-photon absorption rate which gives singly charged ions.
