4-N,N-dimethylamino-4’-N’-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate

DSTMS operates with all conventional types of lasers

      • Telecomm fiber

      • OPA

      • OPCPA

Applications

•  THz generator and detector

•  Multi-THz generator

•  Second harmonic generator

Main Advantages

Superior performance to classical THz generator (ZnTe and Lithium Niobate) from Ti:Sa 800 nm lasers

Comparison with sister DAST crystal

•  DSTMS and DAST have similar optical properties

•  DSTMS optical to THz energy efficiency is slightly higher than DAST

•  DAST could show higher peak electric field because of the broader spectrum than DSTMS

•  DAST has higher damage threshold than DSTMS
