ABSTRACT:
A switching laser comprising, in a cavity, a cell of an amplification gas and a cell of an absorption gas, means for exciting said amplification gas and means for exciting said absorption gas. Said means for exciting the absorption cell comprise a radio frequency AC voltage source pulsed at a certain rate. The laser is namely used for infrared detection.
