Abstract
A laser device includes first and second laser transmitting passages. The first laser transmitting passage in the form of tube has an interior opened at its first and second ends. The second laser transmitting passage has first and second ends. The first end of the second laser transmitting passage is spaced away from but optically connected with the second end of the first laser transmitting passage. This allows that laser transmitted through the first laser transmitting passage is guided into the second laser transmitting passage. Air, on the other hand, is transmitted through the first laser transmitting passage to impinge on the first end of the second laser transmitting passage for cooling.
