Abstract: Disclosed is a method of etching a metallized substrate by excimer laser radiation. The substrate is exposed to a selected gas, e.g., a halogen gas, which spontaneously reacts with the metal forming a solid reaction product layer on the metal by a partial consumption of the metal. A beam of radiation from an excimer laser, e.g. XeF laser operating at a wavelength of 351 nm or XeCl laser at 308 nm or KrF laser at 248 nm or KrCi laser at 222 nm or ArF laser at 193 nm or F 2 laser at 157 nm, is applied to the reaction product in a desired pattern to vaporize the reaction product and thereby selectively etch the metal with a high resolution.

Abstract: A capacitive discharge in cesium vapor is used to realize an externally controllable Q-switch synchronizing the appearance of pulse trains from a passively mode-locked neodymium glass laser with other events occurring on a microsecond time scale.

Abstract: An infrared source producing a coherent output having a spectrally narrow and continuously tunable frequency is described. Such a source uses a four wave mixing process in an alkali metal vapor, wherein the initial input beams to the alkali metal vapor come from two dye lasers. In an alternative mode of operation, tunable ultraviolet output is obtained.
