Development of a high-energy, ultrabroadband Ti:sapphire ring regenerative amplifier

Yamakawa, Koichi

JAERI-Research-2003-017.pdf:0.93MB

We have developed a high-energy, ultrabroadband Ti:sapphire ring regenerative amplifier capable of producing in excess of 20mJ output at a 10Hz repetition rate. The technique of chirped-pulse amplification is used to generate two-color, time-synchronized pulses, with central wavelength separations up to $$sim$$ 120nm and with a total energy of 10mJ by using a regenerative pulse shaping technique.

RBS/channeling analysis of epitaxial films with Nb buffer layer on sapphire substrate

Yamamoto, Shunya; Naramoto, Hiroshi

Nuclear Instruments and Methods in Physics Research B, 190(1), p.657 - 660, 2002/00

 Times Cited Count:2 Percentile:79.33

Epitaxial Cu (111), Al (111) and Sc (0001) films were successfully grown on $$alpha$$-Al$$_{2}$$O$$_{3}$$ (11$$bar{2}$$0) substrates with a high quality Nb (110) buffer layer by electron beam evaporation technique. Films were analyzed by RBS/channeling and X-ray diffraction techniques. The Cu (111) film and Al (111) film on the Nb (110) buffer layer have twinned structure, which is rotated by 180$$^{circ}$$ with each other around the $$<$$111$$>$$ direction. The crystal quality of Cu (111) layer was improved with the increase of Nb (110) buffer layer thickness and then saturates at the high quality after about 2 nm thickness.
