Triplet Extinction Coefficients of Some Laser Dyes II

Abstract

We measured the triplet extinction coefficients T over the laser action spectral region of DODC, DMC, Sulforhodamine B, Rhodamine 575, Coumarin 523, Coumarine 521 Coumarin 504, Coumarin 498, Coumarin 490, LD466, bis-MSB, BBO, and OLIG0415. We employed the different lines from an argon and a krypton ion cw laser for excitation. McClure's method was again employed to measure the triplet extinction coefficients. We provide a simplified derivation of McClure's equation. The triplet extinction coefficient of Rhodamine 575 was also measured by using the depletion method and improving it by reconstructing for true triplet-triplet absorption. The value obtained is in good agreement with the one obtained by McClure's method. Keywords: Laser dyes, Rhodamine, Coumarin. (MJM)
