We have demonstrated the photon-stimulated surface spectroscopy using broadband vacuum ultraviolet (VUV) emissions from a laser-produced plasma, in which adsorbed atoms or molecules on material surfaces were to be desorbed and dissociated as a result

We have observed an optical gain at the wavelength of 126 nm in an Ar excimer (Ar 2 * ) amplifier by utilizing a femtosecond vacuum ultraviolet (VUV) seed beam tuned at 126 nm. The maximum optical gain value of 1.1 cm -1 with a spatial distribution i

We successfully achieved the poly-crystallized coatings of bio-active hydroxyapatite on titanium plates. We used several ceramic HAp targets sintered at a temperature of 500°C, 700°C, 900°C and 1100°C, and irradiation by KrF excimer laser at a fl

Microstructure formation of cone-like protrusions (CLP) on titanium (Ti) plate by the femtosecond laser ablation is reported. The number of the laser pulses to irradiate the Ti plate was varied from 10 to 230 at average laser fluence of 0.75 J/cm2 pe

Plasma diagnosis revealed that the electron density of an optical-field-induced Ar 2 * amplifier was larger than 1018 cm−3 after 100 ns of the plasma production, which resulted in the 126 nm optical gain of 1.1 cm−1.
