✦ Synopsis

The temporal characteristics of the Q-switched Nd-glass laser have been numerically investigated. A mathematical model describing the dynamic emission and di erent physical processes has been adapted. This model allows the investigation of the nonlinear saturable absorber e ects on the mode characteristics of the Nd-glass laser, and studying the a ects of the laser input parameters on the output laser pulse characteristics.

Numerical solutions of a nonlinear rate equation system predict the generation of nanosecond pulses of Q-switched Nd-glass laser. The solutions estimate the laser density and the relative population inversion of the Nd-glass laser rod and saturable absorber for di erent emission regimes. The estimated results of the laser output pulse characteristics are in a good agreement with the other calculated and experimental results.
