Caesar is a title of imperial character. It derives from the cognomen of Julius Caesar, the Roman dictator. The change from being a familial name to a title adopted by the Roman Emperors can be dated to about AD 68/69, the so-called "Year of the Four Emperors".
Kaiser is the German title meaning "Emperor", derived ultimately from the name of Julius Caesar. Many languages use a descendant of the word Caesar to mean "emperor", such as Russian царь (tsar) and Greek Καῖσαρ (Kaîsar).
