Researchers Test Galaxy-Seeking Robots

A telescope project from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) will use a planned array of 5,000 galaxy-seeking robots to produce a 3D map of the universe. Dubbed ProtoDESI, the scaled-down, 10-robot system will help scientists achieve the pinpoint accuracy needed to home in on millions of galaxies, quasars, and stars with the Dark Energy Spectroscopic Instrument (DESI).

SLED-Based Broadband Near-Infrared Source

Avo Photonics (Horsham, PA) design, development, and manufacturing, was commissioned by Luxmux Technology Corporation, to develop and manufacture a solid-state, broadband, continuous emitter for use with their line of miniature integrated spectrometers. The emitter combines the outputs of multiple super-luminescent LEDs (SLEDs) into a polarization-maintaining single-mode fiber. Such an accomplishment required collimating multiple beams and achieving collinearity to an overlap of 700 um and pointing to within 250 urad. The result is a >100 mw, fiber-coupled source with continuous emission over the 1250 – 1750 nm band. To learn more, click here.

Short Pulse Seed Laser Diode Driver

Analog Modules, Inc. (Longwood, FL) recently released its short pulse seed laser diode driver, Model 766. The Model 766 offers user-adjustable pulse width capability as low as 150ps up to 1ns for driving 14-pin butterfly packaged laser diode modules at output currents up to 1.1A. Applications include seeding fiber lasers for materials processing, time-resolved spectroscopy, LIDAR and others. The driver circuitry operates from a single 5V power source. All other needed voltages are generated on the board by high efficiency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 3A and voltage capability of 4.2V.

Core Alignment Fusion Splicer

Furukawa Electric (Tokyo, Japan) and OFS (Norcross, GA) recently introduced the FITEL S179 Hand-Held, Core Alignment Fusion Splicer. The FITEL S179 Fusion Splicer can be used on all Metro, LAN and FTTx fibers, including ultra-bend insensitive fibers. The FITEL S179 Fusion Splicer’s large-capacity battery system allows 200 splicing cycles (splicing/heating) in one charge. A 4.3-inch wide LCD screen with touch panel offers easy and intuitive operation and a proportionately wide splicing chamber makes optical fiber easier to load. For improved visibility in low-light conditions, 3 +1 LED lights illuminate the entire splicing chamber. To learn more, click here

Researchers Film Droplets Getting Blown Up by X-ray Laser

This illustration shows how an ultrabright X-ray laser pulse (orange beam) vaporizes part of a liquid jet (blue), creating umbrella-shaped films of liquid and sending shock waves through the jet (bright stripes at top and bottom). (SLAC National Accelerator Laboratory) Researchers have made the first microscopic movies of liquids getting vaporized by the world’s brightest X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory. The new data could lead to better and novel experiments at X-ray lasers, whose extremely bright, fast flashes of light take atomic-level snapshots of some of nature’s speediest processes.

Engineers Set New World Record in Solar Cell Efficiency

A diagram of the spectrum-splitting, four-junction mini-module developed at UNSW. (Courtesy of UNSW) A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device. The record was set by Dr Mark Keevers and Professor Martin Green, Senior Research Fellow and Director, respectively, of UNSW’s Australian Centre for Advanced Photovoltaics, using a 28-cm2 four-junction mini-module – embedded in a prism – that extracts the maximum energy from sunlight. It does this by splitting the incoming rays into four bands, using a hybrid four-junction receiver to squeeze even more electricity from each beam of sunlight.
