Effect of pH on dyehyphen;laser output power

摘要

Experiments have been performed to measure the output power of stimulated emission from acidified or basified solutions of xanthene dyes pumped by a N2laser. The results showed the laser output power was improved for rhodamine 6G, rhodamine B, pyronin B, fluorescein disodium salt, and fluorescein dipotassium salt by factors of 2.2, 2.8, 1.7, 26.7, and 8.6, respectively.
