We report on frequency doubling of the 647.1 nm line from a mode-locked Kr+ laser in a single-mode fiber with pure Ge-doped core. The harmonic light at 323.5 nm builds up after about 20 min of laser irradiation at 647.1 nm. Peak powers as low as 600 W were sufficient to prepare the fibers for second harmonic generation.

    In our previous studies, we confirmed that low-level laser therapy (LLLT) with a 980-nm gallium-aluminum-arsenide diode laser was beneficial for the healing of the alveolar bone in rats with systemic disease. However, many factors can affect the biostimulatory effects of LLLT. Thus, we attempted...
