Question

6. A GaAs and a GaP laser are doped with the same Ga concentration of 1026/m3. They are also Pumped the same, and have 0.1% of the Ga concentration in the upper laser level. Determine the radiated power of a cubic volume 10 mm emitted by each of these laser. The upper level lifetimes of GaAs and ĢaR are 230 s and 230 us, respectively and the emission wavelength, of both, is 530 om, Calculate the radiated power per unit frequency if al radiated power is averaged over the FWHM emission linewidth of each transition
