We demonstrated 0.9 mJ terahertz pulses by optical rectification of a high-energy Cr:Mg2SiO4 laser in large organic crystal. The emitted spectrum covers 0.1–5 THz and the peak fields exceed 42 MV/cm and 14 Tesla.
We have demonstrated a quantum interface based on the frequency upconversion for photons carrying orbital angular momentum (OAM) states from telecom wavelength to visible regime by sum-frequency generation with high quantum conversion efficiency.
We report on a single-frequency nested cavity OPO based on OP-GaAs, pumped by a pulsed Tm:YAP microlaser. The threshold energy is 10 μJ and temperature tuning enables to cover the 10.3–10.9 μm range.
