Power supply for carbon dioxide lasers
Abstract
An improved ac power supply for a CO2 laser which eliminates the need for ballast resistors to excite a stable discharge is disclosed. The method involves the connection of an inductance in front of the rectifier. This procedure provides a nondissapative positive resistance effect for cancelling the negative differential resistance exhibited by the tube at frequencies below 2 KHz. Such an inductance setup also increases the efficiency of the system.
