| Outline of Final Research Achievements |
Organic DAST crystal has much larger nonlinearity and faster response time compared to those of conventional inorganic materials. We aim to measure ultra-short pulse electron beam bunching by using electric-optical effect in DAST.
Quality of DAST crystals was improved by optimizing solution grwoth method. Moreover, we have developed special process method for fragile DAST crystals using diamond edge to optimize shape of DAST crystals. Besides, off-line measurement system was developed to evaluate E-O effect capability in DAST in detail.
Consequently, we have demonstrated E-O measurement and sucessfully measured eletron beam bunching with femto-time scale using DAST.
