Paper Abstract

We report on the use of a compact Er-Yb:glass laser Q-switched by an AOM for seeding two-stage optical parametric amplifier realized in a single PPKTP crystal. We have generated 5 ns long pusles with a pulse energy exceeding 0.5 mJ. The parametric signal generation efficiency in the second amplification stage was 27%, while the pump depletion reached 39%. The two-stage OPA peak power gain was 30.1 dB for the seeding peak powers of 100W, while the gain reached 81 dB for the lowest seed peak powers of 0.7 mW. The OPA generated a diffraction-limited signal beam while maintaining the original spectral width of the seen.
