Explanation:
Given The wavelength of emission is 6000 Å and coefficient of spontaneous emission is 10^6/s. Determine the coefficient for the stimulated emission
- We need to find the coefficient for the stimulated emission.
- So coefficient of stimulated emission will be
- B 21 = c^3 A 21 / 8 π h v^3
- So we have A 21 = 1/τ and λ^3 = c^3 / v^3
- So B 21 = λ^3 / 8 π h τ
- = (6000 x 10^-10)^3 m^3 / 8 x 3.14 x 6.626 x 10^-34 Js x 10^-6
- = 216 x 10^9 x 10^-30 m^3 / 166.44512 x 10^-40 Js^2
- = 1.29 x 10^19 m/kg
