This paper presents for the first time the modeling and experimental efforts to classify the electric instability modes of the Cassie-state droplets on super-lyophobic surface. The shape of the liquid-air interface on overhanging pillar structure, un

Large-scale vortical structures and associated mixing in methane/air swirling coaxial jets are actively controlled by manipulating the outer shear layer of the outer swirling coaxial jet with miniature flap actuators. In order to investigate the cont

Convective boiling in transparent single microchannels with similar hydraulic diameters but different shaped cross-sections was visualized, along with simultaneous measurement of the local heat transfer coefficient. Two types of microchannels were te

Active control of a lifted flame issued from a coaxial nozzle is investigated. Arrayed micro flap actuators are employed to introduce disturbances locally into the initial shear layer. Shedding of large-scale vortex rings is modified with the flap mo

This is a report on the mode-locking stability of a Kerr-lens mode-locked Ti:sapphire, measured by a newly developed noise measurement method. Mode-locking stability is monitored via a power spectrum, which is obtained by irradiating optical pulses o

A large Ce3+:LiCaAlF6 (Ce:LiCAF) crystal with 15 mm diameter was grown successfully by the Czochralski method. Owing to its large size, 60 mJ, 289 nm pulses were generated directly from a quasi-coaxially pumped Ce:LiCAF laser. In addition, a new nonc

A table-top sized hybrid fluorescence spectroscopy system with picosecond, 3-MeV electron-beam from a photocathode and picosecond optical pulses was successfully demonstrated. This system has shown that the properties of an electron-beam pumped Ce:Li

A two-crystal, pump and probe scheme is established allowing the evaluation of potential laser materials with unknown gain and loss properties. Using a streak camera coupled to a spectrograph, the time-resolved gain or loss spectra are obtained using

To develop high-peak-power ultrashort pulse laser systems in the ultraviolet region, a large Ce/sup 3+/:LiCaAlF/sub 6/ (Ce:LiCAF) crystal, a tunable ultraviolet laser medium with large saturation fluence and broad gain spectrum width, was grown succe
