Abstract
A high power, closed cycle photolytic atomic iodine laser system having a high molecular weight gas as a laser fuel and which requires a high velocity flow of the laser fuel, the laser fuel to be in a selected low pressure range, and the laser fuel to be of very high purity. The laser system has a turbo-molecular blower for circulating the laser fuel. The turbo-molecular blower provides the high velocity flow, the selected low pressure through the laser gain cell, and a high compression ratio. The velocity is in a range of about 1 m/s to 100 m/s, the compression ratio being in a range from about 10:1 to 1000:1, the selected low pressure in a range of about 5 to 60 Torr, and the turbo-molecular blower not contaminating the laser fuel of the closed cycle fuel system by the use of ferrofluidic rotary seals. The turbo-molecular blower has a blower assembly that provides a continuous, high velocity and pressurized gas flow. The turbo-molecular blower has a housing with at least one inlet and at least one outlet for the laser fuel. The housing has a cooling source thereabout to reduce heating caused by the high molecular weight gas flowing therethrough. The blower has a motor assembly mo…
