For a double-pass-pumped cw Tm:YAG laser, we developed a theoretical model, taking into account reabsorption loss and mode matching between the pumping light and the cavity mode. We also demonstrated that efficient operation can be obtained with a simple cavity configuration by using a dichroic output mirror, highly reflective at the pumping wavelength and(More)
A concise total synthesis of spirocurcasone was accomplished. Key features of the synthesis involved a vinylogous Mukaiyama aldol reaction, a Carroll rearrangement of β-keto allyl ester derivative, an intramolecular aldol condensation, and a spiro ring formation by ring-closing metathesis of the pentaene compound. This synthetic work was complete in nine(More)
Dislocation structures and their effect on the superdislocation motion in Ni3Ge single crystals have been studied by two-step deformation. In these tests either octahedral or cube slips were induced by prestraining. A difference in the induced dislocation structure is found to cause a notable change in the second deformation step depending on the(More)
A highly sensitive and broadband method of obtaining thin film permeability without limitations in sample size was developed based on the high-frequency impedance change because of skin effect. A meander-type probe (3.5 mm &#x00D7; 2.5 mm, 2 turns) was placed in proximity of a (Co<sub>25</sub>Fe<sub>75</sub>)<sub>90</sub>B<sub>10</sub> film (45 mm &#x00D7;(More)
