Mechanism for clarifying YAG:V^3+ passive laser shutters accompanying SRS conversion in KGW:Nd^3+ crystals

Dynamics of generation of a pulsed Nd3+:KGd(WO)2/V3+:YAG laser emitting in the self-frequency Raman conversion mode at λ = 1.538 μm

“…Moreover, not one of the studies [7][8][9][10] contained oscillograms of the eye-safe radiation power that gave an idea of the time profile of the Stokes pulses generated with passive modulation of losses. Furthermore, our previous research on lasers with intracavity nonlinear-optical conversion of radiation by SRS methods and parametric light generation showed that the temporal dynamics of such lasers can be rather complicated [13,14].…”

“…These conditions enable generation of both laser and Stokes radiation in a single cavity. The V:YAG Q-switches were set up in the laser cavity in a position for which the Stokes pulse energy was maximal considering that their saturated absorption has polarized anisotropy [7]. The energy of the radiation is measured by PE-10 and PE-50BB pyroelectric energy meters with display of the information on an Ophir Laser Star monitor.…”
