ABSTRACT:
A laser apparatus includes an output mirror and a total reflection mirror. A discharge tube is located between the output mirror and the total reflection mirror. The discharge tube contains laser medium gas. A first block connected to a first end of the discharge tube supports the first end of the discharge tube and also the output mirror. A second block connected to a second end of the discharge tube supports the second end of the discharge tube and also the total reflection mirror. A third block connected to an intermediate portion of the discharge tube supports the intermediate portion of the discharge tube. An optical bench supports the first block, the second block, and the third block. A turboblower connected to the third block is supported by the third block. A first passage connects the turboblower and the first block. A second passage connects the turboblower and the second block. The turboblower draws the laser medium gas from the discharge tube via the third block and returns the laser medium gas to the discharge tube via the first passage, the second passage, the first block, and the second block.
