  "abstract": "A method of obtaining a long-lived flashpumped laser dye with an output equivalent to commercial dyes and a low threshold of lasing using the N-methyl tosylate salt of 2-(4-pyridyl)-5-(4-methoxyphenyl) oxazole.",
  "claims": [
    "1. A method of obtaining in a flashlamp pumped laser system, a long-lived flashpumped laser dye having a low threshold of lasing and a moderate output comprising the steps of: placing a dye solution comprising a laser dye, the N-methyl tosylate salt of 2-(4-pyridyl)-5-(4-methoxyphenyl)oxazole, having the structure: ##STR2## and a solvent into a laser dye cavity; screening said dye solution from ultraviolet light with an optical filter; flushing said dye solution with an inert gas; and optically pumping said dye solution with a flashlamp to produce laser emission.",
    "2. The method of claim 1 wherein said solvent is selected from the group consisting of ethanol and methanol.",
    "3. The method of claim 1 wherein said inert gas is argon."
