As indicated by the solid arrow in the figure, the first discharge '#1
The blower 5 on the left side in the figure and the right side in the figure Come back to Blower 5. In the same way, the gas medium 4 sent from the blower 5 on the right side of the figure is distributed to the left and right from the waste supply port 2b in the center of the second discharge tube 1b, as shown by the solid arrow in the figure. Then, the gas passes through the second discharge tube lb and returns to the blower 5 on the left side in the figure and the blower 5 on the right side in the figure from the gas outlet ports 3b provided at both ends thereof. Returning friend gas medium 4 again the first discharge tube 11% second
The gas medium 4 is sent to the discharge tubes 1b and circulated, but in this conventional laser oscillation device, the gas medium 4 is fed into the discharge tubes 1a and 1b.
Two blowers 5 are installed in the lIP to cool the gas medium 4.
The gas medium 4 circulation requires several parts, such as the need for two exchangers 6. Since the waste medium 4 is supplied and circulated by the two primary blowers 5, the husband's blower 5
It is difficult to maintain the same amount of air flow.
