Description

The experiment P5.8.5.3 introduces to optical pumping as well as emission and absorption. Due to the pumping process spontaneous and stimulated emission is generated. The emission is temporarily as well spectroscopical measured and analyzed. The tuning of the emission wavelength of the pump diode laser due to the temperature allows the recording of the absorption spectrum. From the timely decay of the fluorescence light the lifetime of the excited state is measured and the Einstein coefficient for stimulated emission calculated.
