title: Long-pulse operation of argon lasers.
abstract: The construction and operation of an argon laser suitable for long pulse, low duty cycle operation is described. The laser uses a potassium activated alumina cold cathode, Pyrex bore with ceramic liner, ballast tank at the anode, and a single layer magnetic field coil. Operation at pulses several milliseconds long and at a duty cycle of the order of 1/100 has been achieved for the 1-W output (5145 A, TM(00) mode) laser.
