Lasing was observed in pentane-stabilized vapors of 1,4-di(2-(5-phenyloxazolyl))benzene (POPOP) and 1,4-di(benzoxazol-2'-yl)benzene (BOPBO) pumped by KrF* excimer laser radiation (lambda/sub p/ = 248 nm). An investigation was made of the dependences of the threshold pump power density W/sub p.th/ on the pentane pressure, on temperature, and on the vapor pressure of the lasing substance at pump wavelengths lambda/sub p/ = 248, 308, 337, and 350 nm. In the case of BOPBO the minimum threshold power density was W/sub p.th/ = 250 kW/cm/sup 2/.
