1064 nm pumped CdSiP2 optical parametric oscillator generating sub-300 ps pulses near 6.15 µm at 1-10 kHz repetition rates

Here we present a short cavity singly resonant optical parametric oscillator (OPO) emitting ~400 ps pulses in the interesting for medical applications wavelength region near 6.1 μm which is not accessible by oxide based nonlinear materials.
