Decomposition inhibitor, thin film, laser oscillation element, and method for suppressing decomposition of laser dye

摘要

Laser dye degradation inhibitor that meets Es1 (EM) ETN (EM) and ETN (EM) > ET1 (TR). Es1 (EM) and ETN (EM) are the lowest excited singlet energy level of the laser dye and the excited triplet energy level, Es1 (TR) and ET1 (TR) are the lowest excited singlet energy level and the lowest excitation triplet energy level, and N is the natural number.
