Abstract

A diode-pumped actively Q-switched Tm³⁺-doped fiber laser is reported generating pulse energies of 800 μJ, pulse widths of 43 ns and peak powers of 17.5 kW. By using the single-oscillator as a pump source for nonlinear frequency conversion, mid-IR pulse energies of 230 μJ are extracted from a ZnGeP₂ (ZGP) optical parametric oscillator (OPO).
