Time characteristics of pulses emitted by a YAG:Nd3+ laser due to the 4F3/2→4I13/2 transition

A numerical solution of the rate equations for a Q-switched YAG:Nd³⁺ laser yielded the time characteristics of the radiation pulses emitted as a result of the ⁴F_3/2→⁴I_13/2(λ = 1.318 μ) transition. In contrast to lasing as a result of the main ⁴F_3/2→⁴I_11/2(λ = 1.064 μ) transition, it was found experimentally that the radiation pulses are characterized by a slower rise and longer duration, in agreement with the calculated results.
