NONLINEARITY PROPERTIES OF CERTAIN RARE-EARTHS MIXED LASER-DYES FROM THEIR REFRACTIVE-INDEXES MEASUREMENTS

This note reports the non-linearity characteristic parameters of certa in laser dyes such as rhodamine-B, rhodamine-6G and pyronine-G(y) diss olved in both methyl and ethyl alcohols mixed with some rare-earths. T he parameters are taken from the measurement of refractive indices at three different wavelengths (F = 486.1 nm, d = 589.3 nm and C = 656.3 nm) and used to identify which dye laser liquid has the lowest optical dispersive power among the three investigated.
