  • Patent number: 4592063
    Abstract: In a pulsed gas laser having a flexible exit gas line, such as polymer tubing, a device is disposed just upstream of the flexible tubing to attenuate certain characteristics of the exit gas before it reaches the flexible line. The device comprises a walled chamber having an inlet and an outlet and constructed and arranged to attenuate the peak pressure waves at the pulse frequency. The device also provides attenuation of temperature and for this purpose is made of a good thermal conductor such as copper. The invention enhances the effectiveness of the flexible polymer tubing exit gas lines and permits a laser to be pulsed at higher pulse frequencies than are conventionally done.
