Abstract:

The present invention provides visible and ultraviolet lasers based on excimer transitions in the diatomic homonuclear halogen molecules. Electron beam pumping of argon and hydrogen iodide gas mixtures produces a strong green emission in diatomic ioding centered at 505 mnm and a full width at half maximum FWHM of the gain spectrum of approximately 15 nm. The transition for the green I2 band is bound-to-free, so a laser on this transition is continuously tunable. The result is a room temperature excimer laser that is potentially tunable over a region of 150 A in the blue-green. Therefore, it is an object of the present invention to provide a visible and ultraviolet lasers based on excimer transitions in the diatomic homonuclear halogen molecules which are continuously tunable and operate at room temperature.
