本文描述采用BeO毛细管限制放电的氩离子激光器。采用BeO放电管已使放电电流密度提高到600安/厘米~2以上,而气体清除率可以略而不计。在没有气体补给系统的情况下,经测试此密封激光器的寿命超过1000小时,而输出功率变化低于10%。总输出功率为1.5瓦,加上磁场以后,可达3瓦以上。上述性能是用内径8毫米,长30厘米,内充0.7乇的压强的等离子体放电管获得的。 This article describes an argon ion laser that uses a BeO capillary to limit the discharge. The use of BeO discharge tube discharge current density has been increased to 600A / cm ~ 2 above, and the gas removal rate can be negligible. In the absence of a gas refill system, the sealed lasers have been tested for a lifetime of more than 1000 hours with less than a 10% change in output power. The total output power of 1.5 watts, coupled with the magnetic field, up to 3 watts or more. The above properties were obtained with a plasma discharge tube having an inner diameter of 8 mm, a length of 30 cm and a pressure of 0.7 Torr.
