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.
Claims5
A switching laser comprising, in a single cavity, a cell of an amplification gas and a cell of an absorption gas, means for exciting the amplification gas and means for exciting the absorption gas, said means for exciting the absorption gas comprising a low power radio frequency AC voltage source pulsed at a predetermined rate so as to interrupt absorption in said laser such that laser emission becomes continuous at said predetermined rate.
