Abstract :
Summary form only given, as follows. The effects of the absorption of the pump light by the first excited singlet state on the output of a Rhodamine 6G cw dye laser are investigated. Experimental results show a change in the incremental photon efficiency with pump wavelength. Theoretical expressions are derived for the output power, including the effects of excited state absorption. By matching experimental and theoretical results, values for the excited state absorption cross sections are found at four different wavelenths.
