Laser action from a 2,6,8-position trisubstituted 1,3,5,7-tetramethylpyrromethene-BF_2 complex: part 3

Abstract

Of the four new pyrromethene derivatives studied, 1,3,5,7,8-pentamethyl-2,6-diethylpyrromethene-BF(2) complex lased ~3 times more efficiently than rhodamine 560 under flashlamp excitation.
