High-power direct green laser oscillation of 598 mW in Pr 3+ -doped waterproof fluoroaluminate glass fiber excited by two-polarization-combined GaN laser diodes
Jun Nakanishi,Yuya Horiuchi,Tsuyoshi Yamada,Osamu Ishii,Masaaki Yamazaki,Minoru Yoshida,Yasushi Fujimoto +6 more
TL;DR: A high-power and highly efficient Pr-doped waterproof fluoride glass fiber laser at 522.2 nm excited by two-polarization-combined GaN laser diodes is demonstrated that will enable this system to make a vivid laser display, a photocoagulation laser for eye surgery, a color confocal scanning laser microscope, and an effective laser for material processing.

Single-mode visible laser oscillation in Pr-doped double-clad structured waterproof fluoro-aluminate glass fibre
Shota Kajikawa,T. Terao,Minoru Yoshida,Shinji Motokoshi,Osamu Ishii,Masaaki Yamazaki,Yasushi Fujimoto +6 more
TL;DR: In this article, a double-clad structured waterproof fluoride glass fiber (Pr:DC-WPFGF) was successfully drawn and the laser oscillation was demonstrated, and the maximum output power was measured as 251.7 mW at 639.0 nm.

Control of electrical resistance of TiO2 films by short-pulse laser irradiation
TL;DR: In this article, a femtosecond laser was used to alter the electrical resistances of TiO2 films by attenuating the laser fluence on the film surface, and a range was found in which the electrical resistance of the film was varied even though the morphology of the surface was not changed.
