Abstract

We report efficient generation of picosecond pulses in the near- and mid-IR in the new nonlinear material ${\mathrm{CdSiP}}_2$ pumped at $1.064\mathrm{\mu m}$ by an amplified mode-locked Nd:${\mathrm{YVO}}_4$ laser at a $100\mathrm{kHz}$ repetition rate. By using single-pass optical parametric generation in 8-mm-long crystal cut for type $I(e\to oo)$ noncritical phase matching, an average idler power of $154\mathrm{mW}$ at $6.204\mathrm{\mu m}$ together with $1.16\mathrm{W}$ of signal at $1.282\mathrm{\mu m}$ has been obtained for $6.1\mathrm{W}$ of pump at photon conversion efficiencies of 15% and 23%, respectively. Signal pulse durations of $6.36\mathrm{ps}$ are measured for $9\mathrm{ps}$ pump pulses.
