An automated system for measuring the small-signal gain-vs-wavelength curves for organic laser dyes has been constructed. The system uses a measurement technique reported previously. The data are recorded on a digital recorder. The resulting gain-vs-wavelength curves are plotted on a microfilm plotter.
