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

Exercise 6 The upper laser level lifetime of Nd:YAG and Nd:glass Lasers are respectively 230 μs and 320 us. Assume that both Nd:YAG and Nd:glass laser materials are doped to the same Nd concentration of 1026 /m3. Assume they are both pumped identically, so that they have approximately 0.1% of Nd3+ ions in the upper level. Compare the radiated power of a cubic volume 10 mm on a side from each of these materials. Assume that both materials radiate at...
