| 摘要 |
The invention relates to a gas laser which comprises a flat plate transmission line, for laser excitation formed by an insulating plate (1) placed between two charged metal plates (2,3,7). The line also includes a semi-conductor layer (13) disposed on a surface of the insulating plate to reduce progressively the surface electric field on the insulating plate, from the edge (14) of the metal plate (2,3) to the edge (16) of the insulating plate. Application to remote detection of polluting gases in the atmosphere. |
