Summary form only given. In the field of chemical analysis, the gas chromatograph (GC) has been widely used because of its flexibility, short measurement time and low running cost. Recently, high-sensitive detection is required for further improvement of analytical performance. To realize high sensitivity, excellent detector for GC is needed. Until now, many types of detectors have been developed...
We succeeded in growing single crystal of bis[4-dimethylamino-N-methyl-4-stilbazolium] terephthanate (BDAS-TP) by using a solution-slow-cooling technique. We obtained a broadband THz spectrum from BDAS-TP crystal.
In the present paper, we report the generation of mid-IR short-pulse in spectral range of 10 ~ 40 mum (7.5 ~ 30 THz) using DAST(4- dimethylamino-N-methyl-4-stilbazolium tosylate) crystal and the difference frequency is generated.
A novel low temperature bonding method was developed by using polyurea film as intermediate layers. A microchip having microchannel which has highly hydrophilic surface was realized by the pretreatment of VUV (vacuum ultraviolet) light irradiation. The bonding temperature was low enough to use thermo plastic channel plates such as PMMA (poly-methyl methacrylate) with negligible deformation of the...
We have measured terahertz emission from various organic crystals excited by femtosecond pulses. Our four emitters are 3,5-dimethyl-1-(4-nitrophyenyl)-1,2,4-triazole (DMNT), 3,9-dinitro-5a,6,11a,12-tetrahydro-[1,4]benzoxazino [3,2-b][1,4] benzoxazine (DNBB), 1-(2-thienyl)-3-(4-methyl-phenyl) propenone (TC-28), and 1-(3-thienyl)-3-(4-bromphenyl) propenone (TC-122). Bandwidths of these emitters are...
