LASER CONTROL DEVICE WITH INTERVAL TIMER

摘要

A laser control device (4) includes a pulse repetition interval timer (4d) and a pulse width timer (4b) that, upon each setting, directs one pulse having a predetermined pulse width to a laser system (5) that emits a laser beam in response thereto. A pulse cycle timer (42) is provided which sets the pulse width timer at preset intervals during a time period from its initial setting until the resetting thereof. The pulse repetition interval timer (4d) resets the pulse cycle timer (4c) when a predetermined time has passed since the initial setting time, and an acutator (4a) is provided for simultaneously setting the pulse width timer (4b), the pulse cycle timer (4c) and the interval timer (4d).
