Abstract : To provide a better method of cooling an argon ion laser, the arc-tube was constructed by alternately stacking 52 copper discs (1/8 in. long with a 3/32 in. hole in the center) and 53 viton O-rings. For this design the optimum fill-pressure was experimentally determined to be 0.24 torr and the voltage gradient in the arc-tube was 6.8 volts/cm. Over the discharge current range of 7.5 to 17.5 amperes, the power output varied as I(3.5). By shorting groups of discs together, it was found that metal tube lasers can be constructed of segments with length-to-bore ratios of up to 11.33. (Author)
