Abstract:
A light-pumped dye Laser having input and output paths parallel and the input radiation deflected into the cavity at an angle less than 90*, the sides of the cavity being reflective and inclined so that the input radiation travels by repeated reflections along the cavity without reaching the end.
Abstract:
Apparatus providing in sequence a heat source for directing a flow of air under pressure at a temperature in the range of 250* to 800*C, a blower to direct a flow of cool air and a drive mechanism to produce motion between the heat source and blower relative to a resinous material to be cured at a speed whereby the material reaches a temperature of at least 170*C within a time interval of less than one minute and is then cooled.
