在本研究中，充分利用超快雷射之極短脈衝和極高之瞬間功率分別應用在高頻光致電流及雙光子螢光上，由於超快雷射之超短脈衝和極寬的頻寬等特性，可產生大於1.8THz之頻寬，故可用來檢測高速元件；而利用腔內倍頻之光參數振盪器極高之瞬間功率及UVB短波長來取得紫外螢光訊號，並期待UVB的激發卻不受UVB破壞之影響。

In this study, the characteristic properties of the ultrafast laser exhibit sufficiently in the application of RFOBIC and two-photon UV fluorescence. This laser can be used to measure photonic components with fast responding speed due to the ultrashort pulse and broad bandwidth which is RF bandwidths of greater than 1.8THz.
we have demonstrated the use of a frequency-doubled femtosecond optical parametric oscillator in generating two-photon excitation that is equivalent to ultraviolet(UV) light with wavelength less than 300 nm. This capability allows observation of some amino acids and enables excitation that is only possible with wavelength in UVB range(290 nm-320 nm)
