摘要：

We investigated Terahertz generation in organic crystals DSTMS, DAST and OH1 directly pumped by a Cr:forsterite laser at central wavelength of 1.25 mu m. This pump laser technology provides a laser-to-THz energy conversion efficiency higher than 3 percent. Phase-matching is demonstrated over a broad 0.1-8 THz frequency range. In our simple setup we achieved hundred mu J pulses in tight focus resulting in electric and magnetic field larger than 10 MV/cm and 3 Tesla. (C) 2015 Optical Society of America
