Characteristics of passive q-switching laser pulse as a function of cavity decay rate

الملخص EN

The characteristics of passive Q- switching laser pulse have been simulated as a function of cavity decay rate (γc).

The simulation performed by numerical solution for passive Q-switching rate equations model for Cr : YSO (Cr4+ : Y2 SiO5) storable absorber with ruby laser.

This study shows that the photon number, energy, and duration for output laser pulse are decreasing when the cavity decay rate increasing.

The study explained that to a high dissipation of photons by absorption, reflection and scattering mechanisms per round-trip transit time in the cavity.
