Abstract
A new class of laser dyes has a lasing compound syn (R.sub.1, R.sub.2) bismanes that shows efficient laser action under flashlamp excitation. In the laser action spectral region there is little or no triplet-triplet absorption so that laser efficiencies in the range of 1 to 3 percent can be provided. Good solubility in many solvents (especially water) good photochemical stability and simplicity of preparation are inherent in this new lasing media.
