对质子转移激光染料2-（2-羟基苯基）苯并噻唑（HBT）的稀释薄膜的光泵测量表明，它表现出更好的受激发射性能，特别是在高掺杂浓度（26wt%）时。这表明，除了广泛调谐增益波长的固有潜力之外，HBT还具有形成高增益介质的能力。两者都有利于克服极化子吸收问题，这是制造有机激光二极管的主要障碍。
Photopumping measurements for the dilute thin films of the representative proton-transfer laser dye, 2-(2-hydroxyphenyl)benzothiazole (HBT) revealed that it exhibited better stimulated-emission performance, especially at the high doping level of 26wt%. This suggests that HBT has an ability to form high gain media, in addition to an inherent potential for widely tuning gain wavelength. Both are advantageous for overcoming the polaron-absorption problem that is a major obstacle to making organic laser diodes.
