をＣＯＴ（三重項消光剤）によって素早く基底状態に戻
す。It is known that when light is irradiated on a dye in a dye solution, the dye excited by the light undergoes a relaxation process and partially accumulates in a triplet having a long excitation life, thereby lowering the laser oscillation efficiency. The dye in the triplet state is quickly returned to the ground state by COT (triplet quencher).
