Efficient 2.87 μm fiber laser passively switched using a semiconductor saturable absorber mirror

A passively switched Ho3+, Pr3+ codoped fluoride fiber laser using a semiconductor saturable absorber mirror (SESAM) is demonstrated. Q-switching and partial mode-locking were observed with the output power produced at a slope efficiency of 24% with respect to the absorbed pump power. The partially mode-locked 2.87 µm pulses operated at a repetition rate of 27.1 MHz with an average power of 132 mW, pulse energy of 4.9 nJ, and pulse width of 24 ps.

Tab. 1: Längenänderungen der Gletscherenden 1986/87

Der niederschlagsreiche, durch mehrere Schadenshochwasser gekennzeichnete Sommer 1987 hat die Nachmessungen an den Gletschern nicht behindert. In 16 Berichten aus elf Gebirgsgruppen wurden die Beobachtungs- und Meßergebnisse von 125 Gletschern vollständig und in bewährter Weise mitgeteilt. Die Originalberichte sind im AV-Gletschermeßarchiv in Innsbruck eingestellt.

Mineralogy and geochemistry of volcanic ash at Japan Trench from DSDP Legs 87 and 57

Volcanogenic sediments were obtained from Site 584, located on the midslope of the Japan Trench. Occurrences of volcanic ash in the diatomaceous mudstones increase within sediments dated 6-3 Ma. The frequency pattern and the sediment accumulation rate obtained at Site 584 are similar to those of Site 440 and to those of Sites 438 and 439, located on the upper slope basin. Explosive volcanism increased during the Pliocene and late Miocene in relation to the intrusion of Tertiary granites and uplift of the Tohoku Arc (northeastern Japan Arc). Hygromagmaphile element concentration shows that the glass does not belong to a unique series, and a comparison with Nankai Trough data distinguishes at least two different evolutionary lines.

Alimentación y desarrollo infantil I: el estado nutritivo de los niños en edad escolar de un suburbio madrileño (Rev Clin Esp 1944; XII:87-94)

El estudio clínico del estado nutritivo de un grupo de niños en edad escolar, habitantes de un suburbio madrileño revela la existencia, relativamente rara, de signos carenciales específicos, que contrasta vivamente con el considerable retraso que se observa en su desarrollo somático. Los hechos parecen demostrar que el problema nutritivo de estos niños es sobre todo un problema cuantitativo. El retraso de la evolución está en relación con la insuficiencia global de la dieta y con el déficit de calcio que es probablemente el elemento individual con mayor grado de carencia en las dietas. La anemia que presenta el 98% de los niños no parece deberse únicamente a una deficiencia de hierro porque la dieta parece tener una cantidad adecuada; probablemente esté más en relación con el exiguo contenido de proteínas animales de la ración.

Transmission Spectra of Rb 87 atoms near an Optical Nanofiber.

We present measurements of the transmission spectra of 87Rb atoms at 780 nm in the vicinity of a nanofiber. A uniform distribution of fixed atoms around a nanofiber should produce a spectrum that is broadened towards the red due to shifts from the van der Waals potential. If the atoms are free, this also produces an attractive force that accelerates them until they collide with the fiber which depletes the steady-state density of near-surface atoms. It is for this reason that measurements of the van der Waals interaction are sparse. We confirm this by measuring the spectrum cold atoms from a magneto-optical trap around the fiber, revealing a symmetric line shape with nearly the natural linewidth of the transition. When we use an auxiliary 750 nm laser we are able to controllably desorb a steady flux of atoms from the fiber that reside near the surface (less than 50 nm) long enough to feel the van der Walls interaction and produce an asymmetric spectrum. We quantify the spectral asymmetry as a function of 750 nm laser power and find a maximum. Our model, which that takes into account the change in the density distribution, qualitatively explains the observations. In the future this can be used as a tool to more comprehensively study atom-surface interactions.
