Outline of Final Research Achievements |
We aimed to realize a novel coherent light source, namely, a broadly-tunable vacuum ultraviolet (vuv) laser with an optical-frequency-standard precision. First, we developed the injection-locked continuous wave Ti:s laser which can emit a variety combinations of two frequencies. Next, to transfer an optical-frequency-standard precision to these two frequencies, we also developed the new optical technology which accurately divide an optical frequency into three. Furthermore, we have numerically shown that by employing such laser radiations, high-order stimulated Raman scattering process can be artificially controlled and a frequency conversion to a specific high-order Raman mode in the vuv region can be realized with near unity quantum conversion efficiency.
