UV Second Harmonic Generation at 266 nm in He+ Implanted β -BaB2O4 Optical Waveguides
(2008)Optics ExpressWe report on the second harmonic generation of deep UV light in β-BaB2O4 (BBO) waveguides pumped by a frequency-doubled continuous-wave Nd:YAG laser. An output power of 0.32 mW at 266 nm has been achieved for an internal pump power of 670 mW. Optical channel waveguides in BBO crystals were produced by He+ ion implantation, lithographic masking and ion etching. The linear and nonlinear optical properties and the power handling capability ...Journal Article -
Optical properties of 4-N,N-dimethylamino-4′-N′-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate crystals at terahertz frequencies
(2008)Journal of the Optical Society of America BWe have measured the optical properties of 4-N,N-dimethylamino-4′-N′-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate (DSTMS), a highly nonlinear organic crystal, in the terahertz (THz) spectral range. The conditions for efficient THz pulse generation through optical rectification of near-infrared pulses have been calculated and confirmed experimentally. The results show that DSTMS as a source of THz radiation is superior to ...Journal Article -
