abstract

Intense Terahertz radiation in organic crystals is typically generated by optical rectification of short wavelength infrared femtosecond lasers between 1.3 and 1.5 μm. In this wavelength range high energy ultrashort pump sources are hardly available. Here we present results on powerful THz generation by using DAST and DSTMS pumped directly by the widely used and well-established Ti:sapphire laser technology, emitting at 0.8 μm. This approach enables straightforward THz generation by optical rectification. We present systematic studies on nIR-to-THz conversion efficiency, damage threshold, and on the emitted THz spectrum and field strength. © (2014) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
