The dye DDI (1,1'-diethyl 2,2'-dicarbocyanin iodid) dissolved in DMSO (dimethyl sulphoxid) was used in giant pulse ruby laser pumped DFB laser configuration. Wide generation band, narrow (0.1 cm-1) bandwidth, high power as 1.33 MW at the peak of the tuning curve and power conversion factor as high as 30% was found.
