Abstract

We report the operation of an in-line $\mathrm{Nd}:\mathrm{YAG}$ resonator using self-pumped phase conjugation in ${\mathrm{Cr}}^{4+}:\mathrm{YAG}$ at $\lambda =1.064 \mathit{\mu }\mathrm{m}$ in the nanosecond regime. The output beam has a high-quality diffraction-limited ${\mathrm{TEM}}_{00}$ mode and a pulse shape of $\sim 15 \mathrm{ns}$, showing the self-$Q$-switching ability of the resonator. A maximum extraction of $18 \mathrm{mJ}$ and a maximum reflectivity of 2.0 are measured. A transient model provides insight into the energy characteristics and the dynamics of such an in-line resonator.
